Question

The midpoint of QR is (4, -1).
Q = (3.1)
What are the coordinates of point R?

Answer 1

(5,-3)

Explanation:

Given that,

The coordinates of Q = (3,1)

The midpoint of QR = (4,-1)

We need to find the coordinates of point R.

We know that, according to mid-point theorem,

Let (x₂,y₂) be the coordinates of point R.

So,

So, the coordinates of point R is (5,-3).
