To determine if y varies directly with x, we need to check if the ratio of y to x is constant.
When we calculate the ratio for each pair of values:
(10/2) = 5
(24/4) = 6
(36/6) = 6
We can see that the ratio is not constant. Therefore, y does not vary directly with x.
The correct answer is D: no; y does not vary directly with x.
does y vary directly with x?
x| y
2|10
4|24
6|36
A: yes; y = 2x
B: yes; y = 5x
C: yes; y = 7x
D: no; y does not vary directly with x
