Question

If y varies directly with x, write an equation for the direct variation. Find y when x=15 if y=16 when x=30.

Answer 1

As a general rule, "direct variation" is represented by the formula y=kx, where k is called the "constant of proportionality."

y = kx

You are given y=16 when x=30. Please find the value of k.

Now re-write the formula y = kx, using the value of k you've just found.

Finally, let x=15 and find y.
