<u>Answer:</u>
(x,y)→(y,x); A' is at (2, −7)
<u>Step-by-step explanation:</u>
According to the given image, the coordinates of the kite ABCD are:
A (-7, 2)
B(-5, 3)
C(-2, 2)
D(-5, 1)
Kite ABCD is then reflected over the line y = x, the main rule to find the coordinates of the images is (y, x).
So for point A (-7, 2), the coordinates of the point A' after reflecting over the line y=x will be A' (2, -7).

David's score on his fifth test would be an 87. If you add up all the scores from his first to his fourth test, it would 363. However, since there are five tests, in order to get a 90 percent, the sum of all five test scores would be 450. 450 - 363 = 87.
Both lines are parallel, since they have the same slope of 2.
