Find the missing point for the given midpoint and known endpoint.
Midpoint = (-3, 5) and
Endpoint #1 = (0, 0)
Midpoint = { add endpoint x^s / 2 , add endpoint y's / 2 }
Midpoint = (1.5, -7) and
Endpoint #1 = (4, -3)
x coordinate of other endpoint
[ 4 + x ] / 2 = 1.5 mutliply by 2 on each side
4 + x = 3 subtract 4 from both sides
x = - 1
y coordinate of endpoint
[ -3 + y ] / 2 = -7 mutliply by 2 on each side
-3 + y = - 14 add 3 to both sides
y = - 11
Endpoint → ( - 1, - 11 )
See if you can do the others.....
