What is the point coordinate when one of the coordinates is (6,3.4) and the midpoint coordinate is (8,2.2)

Question

I need help with this math problem. I don't understand how to find the answer to these midpoint problems.

Answer 1

consider the formula for midpoint (two of them, one for x, one for y).

 

You can substitute x_mid and x₂ and thus solve for x₁

 

simiarly, solve for y₁
