Answer:y=2x+5
Step-by-step explanation:
Step-by-step explanation:
If y was directly proportional to x, the graph of y against x would pass through the origin (O).
Since the graph above does not show this, y is not directly proportional to x.
(5,4) simply substitute the values in! they work :) hope it helped
