Find the median from D of triangle with vertices D(2,-1), E(0,0), and F(2,5).?

Answer 1

The median from D extends to the midpoint between E and F.

This midpoint is at (1,2.5) or (1, 5/2).

The slope of the median line is

m = [5/2 - (-1)] / (1 - 2) = -7/2

The equation of the median line is

y + 1 = (-7/2)(x - 2) = -7x/2 + 7
y = -7x/2 + 6
7x + 2y = 12

I think that's more than you asked for.

Answer 2

median between D(2;-1) and M(1;2,5). M is middle between E and F
