Question

Determine if the relationship represented is linear. x=5,10,15,20,25,30 and y=50,60,70,80,80,90

I could not find a relationship that worked for all the numbers so I would say it is not linear. Correct?

Answer 1

You are correct. It is not linear over the full domain of x. It is linear from x = 5 to 20; then levels off from 20 to 25, and then is linear again from 25 to 30.

Answer 2

i really have no idea how to do this the x tablr is 4 5 6 7 and the y is 0 -1 -2 -3 plwase help me
