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
