key idea

This is the slope-intercept form for the equation of a line with slope

and

-intercept

solution

First, use the slope

and the point

(

)

to find

the

-intercept.

Substitute

Multiply 1 by

–

Add 2 to both sides of the equation

The slope is 1, and the

-intercept

is 7. Write the equation of the line in slope-intercept form.
