Line segments HG and HJ in xy-coordinate plane both have common endpoint H (-2, 4) and midpoints M1 at (-2, 10) and M2 (8, 5), respectively. What is the distance between M1 and M2? Round to the nearest tenth.
distance formula : sqrt ((x2 - x1)^2 + (y2 - y1)^2) (-2,10)....x1 = -2 and y1 = 10 (8,5)....x2 = 8 and y2 = 5 now we sub d = sqrt ((8 - (-2)^2 + (5 - 10)^2) d = sqrt ((8 + 2)^2 + (-5^2)) d = sqrt (10^2) + (-5^2) d = sqrt (100 + 25) d = sqrt 125 d = 11.18 which equals 11.2 when rounded to the nearest tenths <=
