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.
according to the question, the constant of proportionality is equal to 2. ( 2 pages per hour).
So, the equation becomes;
Therefore, an equation to represent the proportional relationship is;
We can represent the equation on the graph as;
We can also represent it on the table as;
Where x is in hours and y is in pages.
