CCSS.HSA.REI.A.1

The constant value of the ratio of two proportional quantities x and y; usually written y = kx, where k is the constant of proportionality. In a proportional relationship, y = kx, k is the constant of proportionality, which is the value of the ratio between y and x.

• Constant of Proportionality

• Multiplication Property of Equality

• Subtraction Property of Equality

CCSS.HSF.BF.A.1

CCSS.HSF.LE.A.2

A variable that depends on other factors. For example, a test score could be a dependent variable because it could change depending on several factors such as how much you studied, how much sleep you got the night before you took the test, or even how hungry you were when you took it.

• Independent Variable

• Multiplication Property of Equality

• Dependent Variable

• Proportion

The relation between two quantities whose ratio remains constant. When one variable increases the other increases proportionally. (When one variable doubles the other doubles, when one variable triples the other triples, and so on.) When A changes by some factor, then B changes by the same factor: A=kB, where k is the constant of proportionality.
