midpoint of the line segment

Question

The midpoint of the line segment from P₁ to P₂ is (−7,4). P₁ =(−5,9)​, what is P₂ ?

Answer 1

You can use the midpoint formula to solve for coordinates of P₂

(x₁ + x₂)/2, (y₁ + y₂)/2

(-5 +x₂)/2 = -7 to find the x coordinate of P₂

(9 + y₂)/2 = 4 to find the y coordinate of P₂

Give it a try

I got P₂ = (-9, -1)
