The x-coordinate of the midpoint is the average of the x-coordinates
of the ends.
The average of the ends is 1/2(-3+0) = -1.5 .
The y-coordinate of the midpoint is the average of the y-coordinates
of the ends.
The average of the ends is 1/2(-4+2) = -1
The midpoint of the segment is <em>(-1.5, -1)</em>.
The formula for area of a trapezoid is

so you add up the bottom base (17) and the top base (3) to get 20.
you then take the sum of the bases (20) times the height (8) to get 160.
lastly, you take 160 ÷ 2 to get your final answer, which is 80 (:

Because when multiplying by a negative with a negative you will get a positive and multiplying a negative with a positive will get you a negative
