Exercise 11 Page 312

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

Slope: 5
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 slope m and y-intercept b. y=5x-3 ⇒ y= 5x+( - 3) We can see that the slope is 5 and the y-intercept is - 3.
