Question

Is this linear or non linear??

Answer 1

Yes

Explanation:

It's linear because the function here is y=x-1 and these points make up a straight line.

Answer 2

Answer: Linear

Each time y goes up by 4, x goes up by 2

This leads to

slope = rise/run = (change in y)/(change in x) = 4/2 = 2

So the slope is 2.
