Find the variation constant and an equation of variation if y varies directly as x and the following conditions apply.

well, y=kx, so plug in your conditions to find k.

To find the variation constant and equation of variation when y varies directly as x, we need the conditions of the problem.

When two variables vary directly, it means that one variable is directly proportional to the other. Mathematically, it can be expressed as y = kx, where k is the variation constant.

In this case, we need the specific conditions of the problem to determine the value of k. It could be given as an equation or as a set of values where both x and y are known.

Please provide the specific conditions of the problem, and I will be able to help you find the variation constant and equation of variation.
