what is the slope of the line that passes through the points (-6,1) and (4,-4)

Question

e.mccormick · Answer

Slope is change in y over change in x.  So if you do $$\frac{y_1-y_2}{x_1-x_2}$$You will have the slope.
The points give you the x and y values.  So say $(x_1, y_1)=(-6,1)$ and $(x_2, y_2)=(4,-4)$ and there you go.

thank you very much!

It also works if I had chosen the points the opposite way.  As long as my $x_1$ and $y_1$ come from one point, and the 2s come from the other, it works.  NEVER pull say $x_1$ from the first point and $y_1$ from the second.  That will fail.  So once you pick one as the first point, just stick with it and it works.
