A

Step-by-step explanation:

A proportional relationship is a straight line and must always pass through the origin (0,0). Going by this logic, since C is not a straight line, it can be eliminated and since B and D do not pass through the origin (0,0) they can be eliminated as well, which leave us with A, which is a straight line and passes through the origin (0,0).

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.
