Exercise 39 Page 154

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

Slope: -1/2
y-intercept: 7

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= -1/2x+ 7 We can see that the slope is - 12 and the y-intercept is 7.
