    no; y does not vary directly with x As you can see.....y=2x, y=4x and y=8x are not true from the table.

    to vary directly means to increase as it increases as x gets bigger, y gets bigger; so there is some direct variance at play if the ratio between x and y is the same for each point; then you will know the constant of variation looks to be a ration of 8/11 = x/y y = (11/8)x 1.3 ... id go the 3rd option
