Moses · Answer 1

The inverse proportion is PV = k

We can write the equation as P = k/V or P ∝ 1/V. Thus, P and V are inversely related.

We can rewrite V = T/k as V = kT or V ∝ T. Thus, V is directly proportional to T.

F = - kx² is neither a direct nor an inverse relation.

y = kx - 8 is a linear relation, but it is not a direct proportion because of the "-8" term.
