We are given with:
x = L + 9
L proportional to y
x = 24, y = 5
y  = ?, L = 12

Since we know L is proportional to y, we have the equation:
L = ky
Substituting this to the first equation
x = ky + 9
Using the given conditions
24 = k(5) + 9
k = 3
So,
L = 3y
When L = 12
12 = 3y
y = 4

How do you determine if a set of ordered pairs is a function or not?
Serggg [28]
<span>You could set up the relation as a table of ordered pairs. Then, test to see if each element in the domain is matched with exactly one element in the range. If so, you have a function! Watch this tutorial to see how you can determine if a relation is a function.</span>
