Draw a small sketch. You can notice that lines connecting two points points D, E and F (in whatever pair) are parallel to the sides of the triangle, therefore equal gradients. Find those gradients, and then use with points D, E and F where appropriate.

so would i use y2 - y1/ x2-x1 for each of the coordinate pairs to find gradient?

Yep, that is how the gradient is found between 2 points, after all.
