    Answer:

    • y = 1.5x
    • y = 15 when x = 10

    Step-by-step explanation:

    A direct variation equation is of the form …

      y = kx

    for some constant k. We can arbitrarily choose k=1.5, so our equation is …

      y = 1.5x

    For x=10, the value of y is …

      y = 1.5·10 = 15
