The graph appears to go through the points (0, 0) and (1, 3), so has a constant of variation of (3-0)/(1-0) = 3. Its equation would be
... y = 3x
The equation can be rewritten by muliplying by y to get
... y = (10/3)x
The value 10/3 is greater than the value 3, so the appropriate choice is ...
... The equation has a greater constant of variation.
