x: -2, -1, 0, 1, 2

y: 9, 4, -1, -6, -11

What is the function rule?

4 answers

note that y decreases by 5 for each increase of 1 in x.
So, y = -5x + b
since y(0) = -1,
y = -5x-1
this doesnt make sense. can you explain it better steve
Doesn't this make sense to you??

Steve said, "y decreases by 5 for each increase of 1 in x."
