Answer 1

As x goes up by 1, what is y decreasing by

Answer 2

f(1) = 1
f(2) = -3 = 1 - (1)4
f(3) = -7 = -3 - 4 = 1 - 2(4)
f(4) = -11 = -7 - 4 = 1 - 3(4)
Every change in x of 1, results in a change of y of -4.

Answer 3

So the answer would be yes? I knew the changes, I wasn't sure.

Answer 4

yes it's decreasing by the same rate everytime it increases at the same rate

Answer 5

so it's linear

Answer 6

Correct
