Answer:
Yes
Step-by-step explanation:
They are inversely proportional
Means if we increase y then the value of x will decrease and vice versa.
It is proportional.
Following the equation: y=kx, you wil know if the equation is proportional. K in the equation represents the constant, which is 1/15. A non proportional equation would be written as y=kx + b. Hope that helps!
