Learn how to find the rate of change from graph. The rate of change is the rate at which y-values are changing with respect to the change in x-values. To determine the rate of change from a graph, a right triangle is drawn on the graph such that the line of the graph is the hypothenuse of the right triangle. Then the rate of change of the graph is given by the length of the vertical leg of the right triangle divided by the length of the horizontal leg of the right triangle.

Learn how to graph linear equations written in slope intercept form. When given a linear equation in slope intercept form, (i.e. in the form y = mx + c, where m is the slope and c is the y-intercept). We first plot the y-intercept and using the slope, we can determine the rise and the run of the required line and then be able to plot the next point from the y-intercept. We then draw a straight line passing through the two plotted points.

Learn how to find the rate of change from a table of values. The rate of change of a set of data listed in a table of values is the rate with which the y-values are changing with respect to the x-values. To find the rate of change from a table of values we determine the rate at which the y-values are changing and divide it with the rate at which the x-values are changing. i.e. rate of change = change in y / change in x.

Learn how to find the slope between two points. The slope of a line is the steepness of the line. The horizontal line has a zero slope while the vertical line has an undefined slope. To determine the slope of a line passing through two points, we need to know the coordinates of 2 points on the line. Then the slope of the line is given by the quotient of the difference between the y-coordinates and the difference between the x-coordinates. i.e. slope = (y2 - y1) / (x2 - x1).

Learn how to graph linear inequalities written in slope-intercept form. Linear inequalities are graphed the same way as linear equations, the only difference being that one side of the line that satisfies the inequality is shaded. Also broken line (dashes) is used when the linear inequality is 'excluded' (when less than or greater than is used) and a solid line is used when the inequality is 'included' (when greater than or equal to OR less than or equal to is used).
To graph a linear inequality in slope intercept form, we first plot the y-intercept and using the slope, we can determine the rise and the run of the required line and then be able to plot the next point from the y-intercept. We then draw a straight line passing through the two plotted points.
After the line representing the linear equation form of the linear inequality is drawn, we select a point either side of the line to determine which side of the line is true for the given inequality and then shade the side that satisfies the inequality.

For a complete lesson on slope of a line, go to http://www.MathHelp.com - 1000+ online math lessons with your own personal math teacher!
In this lesson, students are asked to find the slope of a line given its graph. To find the slope of a line, students use the formula slope = rise over run. Problems involve lines with positive slopes, negative slopes, slopes that must be reduced, slopes of 0 (horizontal lines), and "no slopes"(vertical lines). Students also learn that the variable "m" is used to represent the slope of a line.
In Algebra, we use the word "slope" to describe how steep a line is, and the slope of a line can be found using the ratio rise over run between any two points that are on that line.
Since the slope of a line is a fraction, remember to reduce your slope if possible at the end of the problem.
The most common mistake made in problems involving the slope of a line is to mess up the sign. To avoid this mistake, we use the following ideas:
- The slope of a line that is going uphill from left to right is positive.
- The slope of a line that is going downhill from left to right is negative.
Note that the slope of a line that is horizontal (flat) is zero, and the slope of a line that is vertical (straight up and down) is 'no slope.'
The variable "m" is used to represent the slope of a line, so if the slope of a line is 2/3, then we say that m = 2/3.
The slope of a line is one of the first concepts that is introduced in the study of linear equations.

Whether you're doing your math homework or trying to figure out how steep a mountain is, the slope of a line is simple to calculate and has many practical uses.
Step 1: Graph the line whose slope you are measuring
Use graph paper to graph the line whose slope you are measuring. Draw the line on standard x-and y-axis.
Step 2: Select two points on the line
Select two points on the line. Calculate where each point falls on the x- and y-axis to determine the exact points.
Tip
Write these points as ordered pairs – two numbers inside parentheses. First the x point, and then the y.
Step 3: Subtract the y-axis locations of the two points
Subtract the y-axis location of the first point from the y-axis location of the second point. The difference is called the "rise."
Step 4: Subtract the x-axis locations of the two points
Subtract the x-axis location of the first point from the x-axis location of the second point. This difference is called the "run."
Tip
Pay attention to negative and positive numbers. A negative slope means the line travels downward, while a positive slope means it rises.
Step 5: Divide the rise by the run to find the slope
Divide the rise in the y-axis by the run in the x-axis to find the slope of your line, an exact measurement of just how steep it is.

Learn how to write the equation of a line in a point-slope form. The equation of a line is such that its highest exponent on its variable(s) is 1. (i.e. there are no exponents in its variable(s)). There are various forms which we can write the equation of a line: the point-slope form, the slope-intercept form, the standard form, etc.
The point slope form of the equation of a line is given by y - y1 = m(x - x1). where (x1, y1) is a point on the line and m is the slope of the line.

Learn how to graph linear equations written in standard form. When given a linear equation in standard form, to graph the equation, we first rewrite the linear equation in slope intercept form, (i.e. in the form y = mx + c, where m is the slope and c is the y-intercept). Next we plot the y-intercept and using the slope, we can determine the rise and the run of the required line and then be able to plot the next point from the y-intercept. Finally, we draw a straight line passing through the two plotted points.
Alternatively, we can determine the x-intercept and the y-intercept of the standard form linear equation by subtituting y = 0, then solve for x and substituting x = 0, then solve for y respectively. Recall that the x-intercept is the value of x when y = 0 and the y-intercept is the value of y when x = 0. After obtaining the values of the x-intercept and the y-intercept, we plot the points on the coordinate plane and then draw a line passing through the points.
