15 cats
What's the difference between proportional and non proportional?
Proportional relationships have a CROC and goes through the origin. Non Proportional relationships do not have a CROC and doesn't go through the origin.
Write the equation of the graph below.

y=2x+3
Determine if the table is proportional or non proportional. Explain your answer.
Non Proportional because it does not go through the origin.
