Learn how to graph lines whose equations are given in the slope-intercept form y=mx+b. If you haven't read it yet, you might want to start with our introduction to slope-intercept form.

Use the power of algebra to understand and interpret points and lines (something we typically do in geometry). Topics you'll explore include the slope and the equation of a line.

To graph a linear equation in slope-intercept form, we can use the information given by that form. For example, y=2x+3 tells us that the slope of the line is 2 and the y-intercept is at (0,3).

To graph a line with a slope of K/L that contains the point (x, y), move K units UP and L units to the RIGHT. Then make sure that the line is going through both points.

Learn how to calculate the slope of the line in a graph by finding the change in y and the change in x. Created by Sal Khan and Monterey Institute for Technology and Education.

Learn how to write the slope formula from scratch and how to apply it to find the slope of a line from two points.
