Question

The midpoint of the line segment from P1 to P2 is (-1,3) if P1 is (-5,2) what is P2

Answer 1

The midpoint of (a,b) and (c,d) is
( (a+c)/2 , (b+d)/2) )

let P2 be (c,d)

for the x value :

(c + (-2) )/2 = -1
c -2 = -2
c = 0

find the y value of P2 in the same way.
Check by finding the midpoint of P1 and P2 using the formula I gave, and make sure you get the point (-1,3)
