Question

Midpoint (10,4) Endpoint (9,-4), find the coordinates of the other endpoint.​

Answer 1

Answer:

(11, 12)

Step-by-step explanation:

Mid point coordinates:

• x = (x₁ + x₂)/2
• y = (y₁ + y₂)/2

Since midpoint and one endpoint given (10, 4) and (9, -4), the other endpoint:

• x₂ = 2x - x₁ = 2*10 - 9 = 11
• y₂ = 2y - y₁ = 2*4 - (-4) = 12

So the other endpoint is: (11, 12)
