To Simplify It Put It In Y=MX+B Form .
Nice. We're not really told which is the right angle. We can tell from the squared distances:



We see
so B is the right angle.
That was preliminary and probably indicated in an associated figure.
Now we want the line through the midpoint of the legs, AB and BC, in standard form.
The midpoint of AB is the average of the coordinates of A and B:

The midpoint of BC is

The line through those points is




That's the answer. Let's check it.
Midpoint of AB is (-2,3), -2 + 8(3)=22 good.
Midpoint of BC is (2,5/2), 2+8(5/2)=22 good.

C is 0.003 and so is a and so is b
Answer:
all the answer choices are correct
Step-by-step explanation:
reflections & rotations dont change any of the angle measures
The greatest common factor of 13 and 39 is 13
