Question

....Help Please.......

Answer 1

line

Explanation:

The graphing option sounds nice...

But lines have the same slope no matter what two points you choose.

You can see that x is going up by the same number (plus 1) each time and the y's are going down by the same number each time (minus 3) so this says no matter what two points you choose you will have the same slope which means it is a line.

Answer 2

linear

Explanation:

The x-values all differ by 1, which is to say they are equally-spaced. The corresponding y-values all differ by -3. When (first) differences of equally-spaced values of y are constant, the function is of first degree, which is to say it is linear.

___

If second differences are non-zero and constant, the function is of second degree, quadratic.
