The slope-intercept form of a line: y = mx + b

The slope-intercept form of a line: y = mx + b. Graph the following family of lines using the graphing calculator:. y = 3x + 2 y = 5x + 2 y = -4 x + 2 y = 1/2 x + 2 All of these equations are written in y = mx+b form. What does m represent in each equation?
