Exercise 5 Page 255

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

Slope: 2
y-intercept: - 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 features of the equation. y=2x-3 ⇔ y= 2x+( - 3) Above, we have highlighted the slope m and y-intercept b. We can see that the slope is 2 and the y-intercept is - 3.
