Question

Find the coordinates of the other endpoint of the​ segment, given its midpoint and one endpoint.​ (Hint: Let​ (x,y) be the unknown endpoint. Apply the midpoint​ formula, and solve the two equations for x and​ y.)

midpoint

​(−3​,5​),

endpoint

​(1​,14​)

Answer 1

(x+1)/2 = -3 and (y+14)/2 = 5

Solve for x and y.
