if y varies directly with x, y=kx.
So, y/x is constant.
It is clear that this is not the case. Especially not y=10x. That would give the table
8|80
16|160
24|240
How ever did you arrive at that answer?
For the data in the table, does y vary directly with x? If it does, write an equation for the direct variation.
8|13
16|26
24|39
A:yes;y=5x
B:yes;y=10x***
C:yes;y=1.625x
D:no;y does not vary directly with x
