Answer 3

Well lets look through it

you need 2 things for a function to be considered linear....you need a constant change in 'x' and you need a constant change in 'y'

Here lets check the 'x' first

x starts at 0 and goes up to 1....thats a change of 1 right?
Then from 1...it goes to 2....another change of 1
and from 2 we go to 3...so another change of 1

Good, that is what we want...1 part is checked

Now, we need to see if 'y' is changing constantly as well

We start at -2 and go to 0....so a change in 2

Then from 2...we go to 4 , good another change of 2...so far so good

And from 2...we go to 4....so another change of 2..perfect....

that means for every time 'x' goes up by 1...'y' goes up by 2

Also known as...a linear function :)
