Question

Graph the line with slope -1 passing through the point (-1,-1)

Answer 1

y=mx + b
Remember “m” is the slope so replace it with -1. Then replace y with -1 ; and x with -1.
-1=(-1) (-1) +b
-1 =1 +b
-2=b
So final equation is
y= -1x -2

Answer 2

`y+x+2=0`

Explanation:

`(y-(-1))/(x-(-1))=-1\\ (y+1)/(x+1)=-1\\y+1=-x-1\\y+x+2=0`
