Exercise 3 Page 260

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

Slope: 4
y-intercept: 10

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= 4x+ 10 We can see that the slope is 4 and the y-intercept is 10.
