Question

How do you know whether a table of values represent a linear relation?

Answer 1

If they increase by the same amount each time.

So E.g. 1 3 5 7 9 (+ 2 each time)

Answer 2

If they increase by the same amount each time.

So E.g. 1 3 5 7 9 (+ 2 each time)

BUT NOT e.g. 1 5 6 8 (+ random each time)
