Answer:
Given the table:
x y
11
21
45 5
Since, the quantity x and y are proportional.
Proportional states that:
if y varies directly to x, then equation is of the form y = rx where r is the constant of proportionality.
We have to find the value of r:
Consider any value of x and y from the given table:
Let x = 11 and y =
Substitute the given values we get;
Divide both sides by 11 we get;
Therefore, the value of constant of proportionality
