Answer:
y doesn't vary directly with x.
Explanation:
To know if y varies directly with x, we need to calcula the value of y over x for every row in the table. So:
x y y/x
17 11 11/17 = 0.647
8 13 13/8 = 1.625
9 15 15/9 = 1.667
10 17 17/10 = 1.7
Since the value of y/x is different for every row, y doesn't vary directly with x
