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
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
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.
when both increaes its direct proportion and when one increase and othe decreases its inverse proportion.
Yes it does rely on direct proportion.

Which type of line shows a direct proportion
Such an equation is called a "proportion".

a proportion is an equation. a / b = c / d cross multiply: ad = bc then solve
