y = kx where k is a non-zero constant is an equation of direct proportionality between x and y.
An equation that states that two ratios are equal is a proportion.
the three kinds of proportions are indirect proportion, direct proportion and thepartitive proportion
No, it is not.
There cannot be a "proportion of something": proportion is a relationship between two things, and how you solve it depends on whether they (or their transformations) are in direct proportion or inverse proportion.
proportion
direct proportion: y=kx inverse proportion: y=k/x
when both increaes its direct proportion and when one increase and othe decreases its inverse proportion.
Yes it does rely on direct proportion.
No, direct proportion does not necessarily need to have a slope of 1. A direct proportionality relationship means that as one variable increases, the other variable increases at a constant rate, which can be represented by the equation (y = kx), where (k) is a constant. If (k = 1), the slope will be 1, but any positive value of (k) will still represent a direct proportion, just with a steeper or shallower slope.

An equation that states that two ratios are equal is a proportion.
Such an equation is called a "proportion".

If it is a straight line through the origin then it represents a direct proportion.
