Exercise 13 Page 312

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

Slope: 0
y-intercept: 4

Practice makes perfect

Equations in slope-intercept form follow a specific format.

y= mx+ b, In the above equation, 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=4 ⇔ y= 0x+ 4 We see above that the slope is 0 and the y-intercept is 4.
