# Math Help - slope between points

1. ## slope between points

I need a few problems solved. It's making me (My program) do one problem at a t ime and I can't move on until it's done but if I don't have these done I am going to fail : (

Find the slope if the pairs are: (8, -2) (9, 2)

2. $m = \frac{y_1 - y_2}{x_1 - x_2}$

do it.

3. How would I solve something like:
-2x+2y=16 same thing as before

4. solve what?

-2x + 2y = 16 has an infinite number of solutions for x and y.
