## VOCABULARY

*:*

**Addition Property of Equality**Adding the same number to each side of an equation produces an equivalent expression.

*:*

**Constant of proportionality**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.

*:*

**Direct Proportion (Direct Variation)**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.

*:*

**Division Property of Equality**States that when both sides of an equation are divided by the same number, the remaining expressions are still equal

*:*

**Equation**A mathematical sentence that contains an equal sign

*:*

**Inequality**A mathematical sentence that contains the symbols >, <, ≥, or ≤.

*:*

**Inverse Operation**A mathematical process that combines two or more numbers such that its product or sum equals the identity.

*:*

**Multiplication Property of Equality**States that when both sides of an equation are multiplied by the same number, the remaining expressions are still equal.

*:*

**Proportion**An equation which states that two ratios are equal.

*:*

**Subtraction Property of Equality**States that when both sides of an equation have the same number subtracted from them, the remaining expressions are still equal.

*:*

**Term**A number, a variable, or a product of numbers and variables.

*:*

**Variable**A letter or symbol used to represent a number or quantities that vary
