Step-by-step explanation:
x= -7 y=0
x= -3 y =-6
y =mx+b
b=-7
-6= -3m -7
-3m = 1
m= -1/3
y= -x/3 -7

Answer:
D brainliest?
Step-by-step explanation:
<span>-1<0
so use 2x+1
2(-1)+1=-2+1=-1
-
</span><span>F(-1) means "Evaluate F(x) when x=-1"
Since -1 is less than 0, this means that F(x) = 2x+1. This is because F(x) = 2x+1 when x < 0</span>
