Answer:
y = 11 x
Explanation:
The relationship between two variables x,y is said to be a proportional relationship if the ratio between the values of the two variables is constant:
(3)
where k is the a constant value valid for all pairs (x,y).
In this problem, we are told that Charmaine earns $11 per hour. Here we call:
y = amount of money earned
x = time
We can see that the relationsip between x and y is proportional. In fact:
- after 1 hour, Charmaine has earned $11 (1)
- after 2 hours, Charmaine has earned $22 (2)
.. and so on
For (1), we find
so k = 11
For (2), we find
so k = 11
So, k = 11 for every pair (x,y), so the two variables have proportional relationship.
Moreover, we can write an equation that relates the two variables re-arranging eq.(3).
