An example of direct square proportion is when a circle is directly proportional to the square of its radius. This example is expressed by an equation stating that the area of a circle is equal to the constant multiplied by the square of the radius. Direct proportion is the relationship between two things in which the quantity of one is directly proportional to the other, without the second quantity being squared. In this type of proportion, the two quantities change by the same factor.

A direct relationship graph is a graph where one variable either increases or decreases along with the other. The general equation for a direct relationship graph is y = mx + b, where "y" denotes the dependent variable, "x" indicates the independent variable, "m" represents the slope of the line and "b" is the y-intercept.

The general formula for direct variation is k equals y divided by x. In this formula, k is a constant quantity and x and y are variables. K is also called the constant of variation, because it stays the same even as x and y vary.
