Question

what if you have one midpoint and one endpoint then how do u solve the equation how do u find the other endpoint

Answer 1

You put it like this: \[(x, y)=((x1+x2)/2,(y1+y2)/2)\]

Answer 2

so if we know the midpoint, then multiply the coordinates of the midpoint by 2 (as it is the average of the two endpoints) and subtract the coordinates from the set of endpoints that we know.

Answer 3

sry, i meant subtract the end points coordinates from the doubled midpoint coordinates.
ex. midpoint(2,3) endpoint (4, 5)
4-4=0
6-5=1
other endpoint is (0,1)
