B) y = 3 = 2х<br><br> Is this relation linear or non-linear? Explain why.
Alika [10]

Answer:

I think you meant: y=3+2x, in that case, this is a linear answer

Step-by-step explanation:

Non- linear would look like this: K=2/3

Linear would look like this: Y=4x+7

Why:

It all comes to what is proportional and what is not.

Hoped this helped!
