Exercise 7 Page 138

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

Slope: 0
y-intercept: 8

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

y= mx+ b Here m represents the slope of the line and b is the y-intercept. Let's rewrite our equation a little bit so that it more closely resembles this format. This will make it easier to identify the features of the equation. y=8 ⇒ y= 0x+ 8 We can see above that the slope is 0 and the y-intercept is 8.
