The median DT goes from point D, which is given, to point T which we have to find. The point T is the midpoint of segment EF.
Use the midpoint formula to find the midpoint. Add up the x coordinates of E and F to get -1+5 = 4 Then divide that by 2 4/2 = 2 The x coordinate of point T is x = 2
Repeat for the y coordinates 8+4 = 12 12/2 = 6 The y coordinate of point T is y = 6
So the point T is (x,y) = (2,6)
---------
We know point D is (-4,-1) We just found point T to be (2,6)
Using the slope formula, the slope is.. m = (y2-y1)/(x2-x1) m = (6-(-1))/(2-(-4)) m = (6+1)/(2+4) m = 7/6 The slope is m = 7/6
Use either the coordinates of D or T. I'll use point T. So (x1,y1) = (2,6) meaning x1 = 2 and y1 = 6
We'll plug m = 7/6, x1 = 2 and y1 = 6 into the point slope equation y-y1 = m(x-x1) y-6 = (7/6)(x-2)
