Exercise 15 Page 312

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

Slope: 1/4
y-intercept: -1/3

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=1/4x-1/3 ⇒ y= 1/4x+( -1/3) We can see that the slope is 14 and the y-intercept is - 13.
