Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or 
where
k is the constant of proportionality
The slope of the linear equation is the same that the constant of proportionality
In this problem we have

so
the slope is 
therefore
The constant of proportionality k is 
First we have to find the median
The median is 19 when we cross off all the numbers
Now we have 11 12 15 16 and 17 in the first quartile
Cross 11 and 12 and cross 16 and 17, off which leaves you with 15
