Y is inversely proportional to x
when y=7 , x=9
work out an equation connecting y and x

y = 63/x

Step-by-step explanation:

This is variation, now to the question.

y <> 1/x 1

the <> is called the constant of proportionality, which will now be replaced by a constant (k)

y = k/x 2

Given that y = 7 and x = 9, we now find k , then use it to form an equation to connect y and x.

Back to 2

7 = k/9, therefore

K = 63. Now put thus back in equation 2

y = 63

---

x

Therefore, the equation connecting y and x is

y = 63/x.
