Question

Which of the following tables represents a linear function?

x 1 1 0 1 1
y −2 −1 0 1 2

x 0 1 2 3 4
y −3 2 0 −2 3

x −2 −1 0 1 2
y 2 0 −1 0 2

x −2 −1 0 1 2
y 3 1 −1 −3 −5

Answer 1

D. x −2 −1 0 1 2

y 3 1 −1 −3 −5

Explanation:

Hope this helps :)

Answer 2

The last table (x −2 −1 0 1 2

y 3 1 −1 −3 −5) represent a linear function.

Explanation:

The last table has a constant rate of chage between the points. None of the others have that. In a couple, there are multiple values of y for a single value of x.
