In order to determine which equation shows direct variation, you take into account that a direct variation is a linear equation that can be written in the following form:

y= kx

here k is a constant fdifferent of zero. By comparing the given options you can notice that only the equation y = 2x

Hence, y = 2x shows a direct variation.
