Equation Represents A Proportional Relationship. Y 15x hope this helps comment below for more questions. If a proportional relationship is described by the set of ordered pairs that satisfies the equation y kx where k is a positive constant then k is called the constant of proportionality.
If y then equals zero then the equation represents a proportional relationship. What is the constant of proportionality. For example if total cost t is proportional to the number n of items purchased at a constant price p the relationship between the total cost and the number of items can be expressed as t pn.
Learn how to write a proportional equation y kx where k is the so called constant of proportionality.
If y then equals zero then the equation represents a proportional relationship. In this case the number k is the corresponding constant of proportionality. For example if total cost t is proportional to the number n of items purchased at a constant price p the relationship between the total cost and the number of items can be expressed as t pn. Represent proportional relationships by equations.
