Exercise 53 Page 79

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+ bLet'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.

The given equation is already in this form. Below we have highlighted the slope m and y-intercept b. y= -1/2x -5/2 ⇒ y= -1/2x+( -5/2) We can see that the slope is - 12 and the y-intercept is (0, - 52).
