Slope is your 2x, so 2x over 1 meaning after you plot (-2,2) on the graph you rise 2 and go 1 to the right, or do the opposite to make the line so go down 2 and one to the left. Hope that helped.

EXPLANATION

2' 3" = 27"

3' 5" = 41"

Multiply the length by the width (in inches) of the painting.

27 * 41 = 1107

We now know that the area of the painting is 1107 $in.^{2}$ Next, multiply the cost per square inch (0.35) by the total amount of square inches (1107).
