Question

9. Use the diagram below to answer #9-12. Given Triangle GHI with G(7, 0), H (-5, 5) and I (1, 9), find the midpoint of HI.

Answer 1

midpoint formula : (x1 + x2) / 2, (y1 + y2) / 2
(-5,5)....x1 = -5 and y1 = 5
(1,9).....x2 = 1 and y2 = 9
now we sub
m = (-5 + 1) / 2, (5 + 9) / 2
m = -4/2, 14/2
m = (-2,7) <=== ur midpoint of HI
