You can put this solution on YOUR website!
Find slope of the two given points.
Pick one of the points and form equation in whichever form you prefer.
Adjust your equation to standard form.


m=%285-%28-1%29%29%2F%28-2-1%29=6%2F%28-3%29=-2;
Arbitrarily choosing point-slope form and (1,-1): y-%28-1%29=-2%28x-1%29;
You finish making the adjustment into standard form.

I will complete this...

y-%28-1%29=-2%28x-1%29
y%2B1=-2x%2B2
y%2B1%2B2x=2
y%2B1%2B2x-1=2-1
y%2B2x=1
highlight%282x%2By=1%29
