The answer would be C because he did not correct his mistakes that he had made
True
Step-by-step explanation:
I double checked it I'm positive
You need to find the slope first. (-9,-4). (3,4)
-4-4= -8
-9-3 =-12. Slope is -8/-12 or 8/12 or 2/3
Perpendicular is the negative reciprocal. Or flip over the 2/3 and make it negative.
The answer is - 3/2
900 is the answer of 2 squared times 15 squared
