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 ​(​-10,​7), endpoint ​(​-17,5​)

Answer 1

Step-by-step explanation:

if mid point (a, b) one end point (c, d) then other end point= ( 2a-c, 2b-d)

midpoint (-10,7), endpoint (-17,5)

other end point= (2×(-10)-(-17), 2×7-5)

= (-20+17, 14-5)=( -3,9)

midpoint (-10,7), endpoint (-17,5)then the other end point= (-3,9)
