<h3>What is propotionality?</h3>

In algebra, proportionality is the equality of two ratios.
A and B are in the same ratio as C and D in the formula a/b = c/d.
When one of a proportion's four quantities is unknown, a proportion is often built up to resolve the word problem.
By multiplying one numerator by the opposing denominator and equating the result to that of the other numerator and denominator, the equation can be solved.
Any relationship that has a constant ratio is said to be proportionate. For instance, the ratio of proportionality is the average number of apples per tree, and the amount of apples in a crop is proportional to the number of trees in the orchard.

Acc to our question-

If two variables' ratios (yx)
(x and y) have the same value as a constant (k=yx)
therefore the ratio's variable (y) in the numerator is the sum of the other variable and the constant (y=k:x).
With a proportionality constant of k, it is claimed that y is directly proportional to x in this instance.

Hence,Directly proportional to x.
