Answer:

y= -x-2

Step-by-step explanation:

y=ax+b

x= -2; y=0 => 0=-2a+b; b=2a

x= -1; y= -1 => -1=-a+b => b=a-1

2a=a-1=> a= -1; b= -2

=> y= -x-2

Answer:

y = -x -2

Step-by-step explanation:

We can find the slope by using 2 points

m = (y2-y1)/(x2-x1)

  = (-3-0)/(1--2)

  = -3/(1+2)

   = -3/3

   = -1

The y intercept is when x=0  The y intercept is -2

y = mx + b where m is the slope and b is the y intercept

y = -x -2
