The variables x and y vary directly. Use the given values to write an equation that relates x and y. x = 5, y = 25 okay so im not 100% sure how to do this

    "vary directly" is the key phrase here this means that the equation will be y = kx, where k is a constant of variation so, we plug in x and y to figure out what k is

    Basically wat @Vocaloid is trying to say is y=whatever times x

    K turns in 10. So the equation is y=10x
