Answer:

  • B(-2, -3)

Step-by-step explanation:

Points given:

  • M(3, -4) - midpoint
  • A(8, -5) - endpoint
  • B(x, y) - endpoint

Use midpoint formula to find the coordinates of B:

  • x = (x1 + x2)/2, y = (y1+ y2)/2

Substitute known values and solve for x and y:

  • 3 = (8 + x)/2 ⇒ 6 = 8 + x ⇒ x = 6 - 8 ⇒ x = -2
  • -4 = (-5 + y)/2 ⇒ -8 = -5 + y ⇒ y = -8 + 5 ⇒ y = -3

Point B is:

  • (-2, -3)
