Question

Determine whether why it varies directly with X if so find a constant of variation Kand write the equation

Answer 1

Does not equally vary.

Explanation:

If you notice from x to y the number going between are not even going throughout the table.

Hope This Helps :)

Answer 2

To find the constants (k)

divide y by x:

11/7 = 1.57

13/8 = 1.625

15/9 = 1.66

17/10 = 1.7

Each answer is different, therefore y does not vary directly with x.
