Question

If p varies directly as q, and p = 5 when q=2, find the equation that relates p and q .

Answer 1

p = (5/2)q

Explanation:

Direct variation can be modeled by the equation ...

p = kq

Filling in the given numbers, we can find k.

p/q = k = 5/2

Then the equation is ...

p = (5/2)q

_____

Another equation relating p and q is ...

p/q = 5/2
