Learn about the slope-intercept form of two-variable linear equations, and how to interpret it to find the slope and y-intercept of their line.

There are three major forms of linear equations: point-slope form, standard form, and slope-intercept form. We review all three in this article.

Slope-intercept form (y=mx+b) of linear equations highlights the slope (m) and the y-intercept (b) of a line. Watch this video to learn more about it and see some examples.

Learn how to find the slope-intercept equation of a line from two points on that line. If you haven't read it yet, you might want to start with our introduction to slope-intercept form.

When we have a linear equation in slope-intercept form, we can quickly find the slope and y -intercept of the corresponding line. This also allows us to graph it.

In this unit, we learn how to write linear equations in different forms to reveal different features of their relationships.

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).

Point-slope is the general form y-y₁=m (x-x₁) for linear equations. It emphasizes the slope of the line and a point on the line (that is not the y-intercept). We can rewrite an equation in point-slope form to be in …
