PLZZ ANSWER THE QUESTION ​

Answer 1

A linear function increases at a constant rate of change, which means that for every 1 unit that x changes, y always changes at a same rate.

For example, if x moves 1, y moves 5 constantly. Every time x moves 1, y moves 5.

In this case every time x in the first table increases by 1, y increases by 6, so that is a linear function.

The second table is not linear because when x increases by 1, y decreases by 1. But the second time, when x increases by 1, y decreases by 2! -2 is not equal to -1.

The third and fourth tables are not linear for the same reasons.

Answer 2

The first one

Explanation:

In mathematics, the term linear function refers to two distinct but related notions: In calculus and related areas, a linear function is a function whose graph is a straight line, that is, a polynomial function of degree zero or one. So going in that order gives you a linear function.
