Exercise 39 Page 320

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

Slope: -1
y - intercept: (0,-13)

Practice makes perfect

Equations in slope-intercept form follow a specific format. y= mx+ b In this format, m represents the slope of the line and b is the y-intercept. Let's rewrite our equation in this format. y=- x-13 ⇒ y= -1x+( -13) We can see that the slope is -1 and the y-intercept lies on the point (0, -13).
