Answer 1

To see if a table of values represents a linear function, check to see if there's a constant rate of change. If there is, you're looking at a linear function!

Explanation:

Answer 2

• linear: y = x+5; 5x +5y = 25
• nonlinear: everything else

Explanation:

If it has an exponent, it's non-linear. (There are other ways it can be non-linear, too, but this is the one applicable here.)
