To determine if y varies directly with x, we need to check if the ratio of y to x remains constant. Let's calculate the ratios for the given data:
32/40 = 0.8
16/28 = 0.57
12/16 = 0.75
Since the ratios are not all equal, we can conclude that y does not vary directly with x. Therefore, the correct answer is:
no; y does not vary directly with x.
For the data in the table, does y vary directly with x? If it does, write an equation for the direct variation.
