Question

The midpoint of PQ is (2,3). If the coordinates of P are (-1,4), find the coordinates of Q
​

Answer 1

Coordinates of Q = (5,2)

Explanation:

Given:

Midpoint of PQ = (2,3)

Coordinates of P = (-1,4)

Find:

Coordinates of Q

Computation:

X = [x1+x2]/2 ; Y = [y1+y2]/2

2 = [-1+x2]/2 ; 3 = [4+y2]/2​

x2 = 5 , y2 = 2

Coordinates of Q = (5,2)
