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.

No, a direct proportion does not have to have a slope of 1. A direct proportion means that two quantities increase or decrease together at a constant ratio, which can be represented by the equation (y = kx), where (k) is a constant. The slope of the line in a graph of a direct proportion is equal to this constant (k); if (k) is greater than 1 or less than 1, the slope will reflect that but still indicate a direct relationship.
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.
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.
Yes it does rely on direct proportion.
