Quadrilateral ABCD is a parallelogram because both pairs of opposite sides are parallel. Slope of a line is defined as the difference in Y divided by the difference in X. It doesn't matter which way you do the subtraction as long as you do it in the same order for both X and Y. So let's calculate the slope of AB A(-5,1) B(-2,5) (1 - 5)/(-5 - (-2)) = -4/-3 = 4/3 Slope BC B(-2,5) C(5,3) (5-3)/(-2-5) = 2/-7 = -2/7 Slope CD C(5,3) D(2,-1) (3-(-1))/(5-2) = 4/3 Slope AD A(-5,1) D(2,-1) (1-(-1))/(-5-2) = 2/-7 = -2/7 So our slopes are 4/3, -2/7, 4/3, and -2/7 Since the slopes of AB and CD are identical, those lines are parallel. And since the slopes of both BC and AD are identical, those 2 lines are also parallel. But since 4/3 * -2/7 = -8/21 which is NOT -1, that means that lines AB and BC are NOT perpendicular, so you don't have a rectangle. But you do have a parallelogram because both pairs of opposite sides are parallel.

Here’s the answer. you’re supposed to use 2900 times the interest rate and then add your original amount of money. now you get 2997.15
