The ratio of the areas would be the ratio of the side lengths squared.
Say the ratio of the side lengths is 1:2, the ratio of the areas would be 1:4. If the ratio of the sides were 2:3, the ratio of the areas would be 4:9.
We know that coordinates are labeled (x,y) The formula to find slope is (Y2-Y1)/(X2-X1) So (2- (-7))/(-6-(-6) undefined because the denominator is zero. The line looks like a vertical line at x=-6
