Use Slope and y-intercept to write an equation.

The graph of an equation in slope-intercept form, y=mx+b, is a line with a slope of m, and y-intercept of b.  You can use this form to write and equation of a line if you know its slope and y-intercept.

Vocabulary Refresher

y-intercept: the y-coordinate of a point where the graph crosses the y-axis.

slope:  the ratio of the vertical change (the rise) to the horizontal change (the run.)
