    Answer:

    y = 4.25x

    Step-by-step explanation:

    Given that y varies directly as x then the equation relating them is

    y = kx ← k is the constant of variation

    To find k use the condition y = 34 when x = 8, thus

    34 = 8k ( divide both sides by 8 )

    k = \frac{34}{8} = 4.25

    y = 4.25x ← equation of variation
