Question

How do you find the coordinates of the other endpoint of a segment with the given N(5,-09), and midpoint M(8, -7.5)?

Answer 1

Let (x,y) be the other endpoint of the line segment.

Then, (x+3)/2 = 2 and (y + (-12))/2 = -1

So, x = 1 and y = 10

The other endpoint of the line segment is (1,10).
