Slope and Slope-Intercept Form Activity Math is Fun

Slope-Intercept Form Any linear equation can be written in the form y = mx + b m = slope b = y-intercept Example of slope-intercept form: y = 2x - 1

Make equation into slope-intercept form 2x + y = 7

Make equation into slope-intercept form 3x – 2y = 4

Make equation into slope-intercept form -4x + 2y = 8

Graphing Slope-Intercept Form Start by graphing the y-intercept on the coordinate plane From the y-intercept, move the rise and run of the slope to plot another point Finally, draw the line that connects the two points.

Example y = 2x - 1

Example y = (3/2)x - 2

Example y = 2x + 4
