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
