Answer: Endpoint = (-4,6)
Step-by-step explanation:
To find any endpoint use the formula

multiply each by 2 to simplify
take the equations and simplify
6+
= 2 -2+
= 4 =
-6 -6 +2 +2
= -4
= 6
To check use the Midpoint formula

Yes, you are correct, because -2 is 2 spaces away from the number line.
I have no clue you have to do something like x2-x1 over y1-y2 and you get yoyu answer from that.
The answer should be 11 since adding all the x’s up before 13 equals 11
