You can put this solution on YOUR website! Graph the line with slope -2 passing through the point (-1,-1).
----------------------
OK, I did that. Now what?
=====================
If you want to do it too, on graph paper plot the given point.
A slope of -2 means each change of 1 in x results in a change of -2 in y.
Plot a 2nd point by add 1 to x, and -2 to y. ---> the point (-1+1,-1-2).
Plot that point.
Draw a straight line thru the 2 points.

You can put this solution on YOUR website!
slope = -2 = -2/1
slope = rise/run = -2/1
rise = -2 = go down 2 units
run = 1 = go to the right 1 unit
Start at (-1,-1)
Move down 2 and to the right 1 to arrive at (0, -3)
This is what it should look like
The stuff in red is to be erased later. It's meant to be a visual tool to see what's going on with the slope.
Though your teacher may want you to visually describe these actions. Ask him/her for clarification.
I used GeoGebra to make the graph. Specifically I used the desktop version, but the web app and phone app are equally useful of course.
Desmos is another option I recommend as well.
Both apps mentioned are free.
