ABC is a triangle has vertices A(-2,-1) B (o,7) C(8,3).Write equations for the three medians of a triangle? ?

Question

Please explain how you solved this problem. I am totally lost! Thank you = )

Answer 1

find mid point of BC line

D[(0+8)/2, (7+3)/2] = D[4,5]

median AD >> line from A[-2. -1]and (D)

y - y1 = {[y2-y1]/[x2-x1] } [x - x1]

y - 5 = {[-1 -5] /[-2 - 4]} [x - 4]

y - 5 = {-6 /-6} [x - 4]

y - 5 = 1 [x - 4]

y - x - 1=0 >>>> AD median

do it like wise for other 2
