Direct square proportion is the relationship between two things in which the quantity of one is directly proportional to the square of the other. In this relationship, the ratio of the first to the square of the second is a constant.
Know MoreAn 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.
Learn more about Data GraphsA scattergram or scatter plot defines a relationship between two variables related to cause and effect. According to the American Society of Quality, a scattergram illustrates pairs of numerical data on graphs with one variable on each axis to explore the relationship between them.
Full Answer >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.
Full Answer >A direct variation graph represents a situation in which two variables increase or decrease at the exact same rate. The line on the graph is a straight line that passes through the origin of the graph. The origin is the point on the graph where the horizontal and vertical axes intersect.
Full Answer >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.
