Answer:

Given, y is inversely proportional to x

or y∝x−1

this is if and only if

y∝1x

y=1xk

Also, we know that if y=6 when x=4

then

6=14k

⇔ multiply both sides by 4

24=k this is our constant of proportionality

this gives us our formula

y=24x

Then consider when y=8

then

8=24x

⇔ multiply both sides by x

8x=24

⇔ divide both sides by 8

x=3
