From the intervals from (-2,0) and (4,7) I am not sure if you are required to use (,) or [,] but I will change my answer if needed.

Answer:
12/36
Step-by-step explanation:
Cuz 12 earned A's so it's 12/, then there are 36 choices so it would be 12/36.
The slope of line PQ is m1 = ( 3 - (-3) ) / (2 - (-2) ); then m1 = 6/4 = 3/2;
In the same way, the slope of line RS is m2 = -7/5;
But (3/2) x (-7/5) = -21/10, which is diferrent from - 1;
So, the lines aren't perpendicular.
