Calculate the other endpoint of the segment with the given endpoint (-3.-2) midpoint, (3,4)

Answer 1

The midpoint of a line segment joining (x₁,y_,) and (x₂,y₂) is [(x₁+x₂)/2,(y₁+y₂)/2].

From that information you should be able to solve this problem.

Answer 2

(9,10)

distance from each end to the midpoint is the same, distances from the x and y values are the same.

3 minus -3 = 6 add 6 to 3 to get the x value of the other end = 9

4 minus -2 = 6 add 6 to the y value of the midpoint to get the other end's y value 4+6=10
