How Do you write T varies directly to Q?

To express that T varies directly with Q, you can write the relationship as ( T = kQ ), where ( k ) is a constant of proportionality. This means that as Q increases or decreases, T will change in the same ratio, maintaining a constant multiple represented by ( k ). If you know the values of T and Q at any point, you can determine the constant ( k ) by rearranging the equation to ( k = \frac{T}{Q} ).
