Given that;
Liana takes 2 pages of notes during each hour of class.
To write a proportional relationship, let x represent the time in class and y represent the number of pages.
![y=kx](https://img.qammunity.org/2023/formulas/mathematics/college/zfnjlk9kn7jg7cyy0nlnepmsiaxj3b2oge.png)
according to the question, the constant of proportionality is equal to 2. ( 2 pages per hour).
So, the equation becomes;
![y=2x](https://img.qammunity.org/2023/formulas/mathematics/high-school/gehxm55opy2qzcw9pvonc2nzrebkjsukj6.png)
Therefore, an equation to represent the proportional relationship is;
![y=2x](https://img.qammunity.org/2023/formulas/mathematics/high-school/gehxm55opy2qzcw9pvonc2nzrebkjsukj6.png)
We can represent the equation on the graph as;
We can also represent it on the table as;
![\begin{gathered} x\text{ y} \\ 1\text{ 2} \\ 2\text{ 4} \\ 3\text{ 6} \\ 4\text{ 8} \\ 5\text{ 10} \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/high-school/7bbpdrr4qc6dnl02uqvyeea1d1j2c635x5.png)
Where x is in hours and y is in pages.
