Exercise 40 Page 154

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

Slope: 1/6
y-intercept: - 8

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 The given equation is already in this form. Below we have highlighted the slope m and y-intercept b. y= 1/6x - 8 ⇔ y= 1/6x+( - 8) We can see that the slope is 16 and the y-intercept is - 8.
