m=-13/4

Explanation:

You want to use the formula m=(Deltay)/(Deltax). Since Deltay=y_2-y_1 and Deltax=x_2-x_1, you can substitute that in.

Now, m=(y_2-y_1)/(x_2-x_1).

Each point you were given is one part of that equation. Let's say the first point is (x_1, y_1) and the second point is (x_2, y_2). Then, we can plug those values into our equation to get:

m=(-6-7)/(3--1)

Simply solving for m, we get:

m=-13/4
