I know that I have to use

m=y^2-y^1/x^2-x^1 which is slope form

then I get: m=1-(1)/-2-10 which I substitue

m= ? is where I get lost

but then I know the next part is:

y=mx+b then I am lost from here on as well

Can someone please help me.

Note that since both points have the same y-coordinate, the line is horizontal, at y=1.

Your work was good, since you got m=0. You got confused, but for no reason. A line with 0 slope is just a horizontal line y=k for some constant k.

Now, if you get something like m=4/0, that is not defined, and is thus a vertical line.

The first thing to check for is whether both points have the same x- or y-coordinate. If so, you're done.
