    y = 5x

    Step-by-step explanation:

    The standard equation for directly proportional equations is y = kx. We can see that y is directionally proportional to x when y = 30 and x = 6 and we need to work out an equation connecting x and y.

    → First step is to substitute in the values

    y = k * x

    30 = k * 6

    → Divide both sides by 6 to isolate k and find the value of k

    5 = k

    k = 5

    → Now we substitute k = 5 back into y = kx

    y = 5x
