Answer:

$z = \frac{q}{2}$

Step-by-step explanation:

$z \infty q$

$z = kq$

$z = 2 \: and \: q = 1$

$2 = k1$

$k = \frac{2}{1}$

$z = \frac{1}{2} q$

$z = \frac{q}{2}$

Answer:

z = 2q

Step-by-step explanation:

The formula for direct variation is ...

z = kq . . . . . k is the constant of proportionality

We can find k using the given values of z and q:

k = z/q = 2/1 = 2

Then the equation connecting z and q is ...

z = 2q
