Exercise 8 Page 312

What do m and b represent in the slope-intercept form?

Slope: -1
y-intercept: 4

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 Let's rewrite our equation a little bit so that it more closely resembles this format. This will make it easier to identify the slope m and y-intercept b. y=- x+4 ⇒ y= - 1x+ 4 We can see that the slope is - 1 and the y-intercept is 4.
