From the given points that are (3,1),(9,3),(27,9), we can say that x is three times of y. That is
x= 3y
And we need to solve for y. For that, we need to get rid of 3 from the right side by dividing both sides by 3 . And on doing so , we will get
[tex] \frac{x}{3} = \frac{3y}{3} [/tex]
[tex] \frac{x}{3}=y [/tex]
or
[tex] y=\frac{x}{3} [/tex]
