Answer:
endpoint is (29, -13)
Step-by-step explanation:
Formula for midpoint is 
So, let
be the coordinates of the endpoint you are looking for.
and
= (10, -3)

-9 +
= 20 7 + 

endpoint is (29, -13)
We substitute in c using 9, it will be as follows:
5 ×[(-6×9)+4] = 5 × (-54+4) = 5 × (-50) = -250
The slope is 1/1
You can use rise over run
Step-by-step explanation:
due to the rules of crossing lines and their angles, the 2 angles opposite of each other must be equal.
so,
7x + 7 = 112
7x = 105
x = 15
