Question

Find the coordinates of the missing endpoint if B is the midpoint of AC. C(-6,-2),B(-3,-5)

Answer 1

Answer:

  A = (0, -8)

Step-by-step explanation:

  B = (A+C)/2 . . . . the midpoint is the average of the end points

  A = 2B -C = 2(-3, -5) -(-6, -2) . . . solve for A, substitute point values

  A = (0, -8)
