Answer: yes
Step-by-step explanation:
1) A graph is linear when the line on a graph is a straight line with no curves.
2) A proportional graph means that as x increases, y increases and when x decreases, y decreases and their ratio always stays the same.
3) (I don't know what type of equation you mean but this is my guess)
Division is the last step of an equation.
The answer might be 45 x 1, because 45 is the greatest factor of 45.
