Exercise 18 Page 142

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

Slope: 0
y-intercept: -1

Practice makes perfect
Equations written in slope-intercept form follow a specific format.

y= mx+ b Here, m represents the slope and b the y-intercept of the line. Let's rewrite our equation a little bit so that it more closely resembles this format. This will make it easier to identify its features. y=-1 ⇔ y= 0x+( -1) We see above that the slope is 0 and the y-intercept is -1.
