Question

Point M is the midpoint of XY. If

the coordinates of M are (-4,3)
and the coordinates of X are (-1,5),
what are the coordinates of Y? Help? Please

Answer 1

d) (-7, 1)

Explanation:

If M is the midpoint of XY, then ...

M = (X +Y)/2

2M = X +Y

Y = 2M -X

Y = 2(-4, 3) -(-1, 5) = (2(-4)-(-1), 2(3) -5)

Y = (-7, 1)
