Question

The midpoint of the line segment from p 1 p 2 is (- 6, 2) . if p 1 =(-8,2) , what is p 2 ?

Answer 1

If we have 2 coordinates (x1,y1) and (x2,y2), the midpoint is given by the following equation:

((x1+x2)/2,(y1+y2)/2)

We have the first set of coordinates which is (-8,2) and we have the midpoint which is (-6,2)..

For the x-coordinate:

(-8+x2)/2=-6

-8+x2=-12
x2=-12+8
x2=-4

For the y-coordinate:

(2+y2)/2=2
2+y2=4
y2=2

So the coordinate p2 will be (-4,2)
