Exercise 15 Page 142

What do m and b represent in y=mx+b?

Slope: -3
y-intercept: 2

Practice makes perfect
Equations in slope-intercept form follow a specific format, where m represents the slope of the line and b is the y-intercept.

y= mx+ b The given equation is already in this form. Below we have highlighted the slope m and y-intercept b. y= -3x+ 2 We can see that the slope is -3 and the y-intercept is 2.
