| Term | Definition |
|---|---|
| Addition Property of Equality | the property that states that if you add the same number to both sides of an equation, the new equation will have the same solution |
| Constant of Proportionality | the constant, k, in proportional equations |
| Dependent Variable | the output of a function; a variable whose value depends on the value of the input, or independent variable |
| Direct Variation | a linear relationship between two variables, x and y, that can be written in the form y = kx, where k is a nonzero constant |
| Division Property of Equality | the property that states that if you divide both sides of an equation by the same nonzero number, the new equation will have the same solution |
| Equation | a mathematical sentence that shows that two expressions are equivalent |
| Independent Variable | the input of a function; a variable whose value determines the value of the output, or dependent variable |
| Inequality | a mathematical sentence that shows the relationship between quantities that are not equal |
| Inverse Operations | operations that undo each other; + and − , or × and ÷ |
| Multiplication Property of Equality | the property that states that if you multiply both sides of an equation by the same number, the new equation will have the same solution |
| Proportion | an equation that states that two ratios are equivalent |
| Solution | a value or values that make an equation or inequality true |
| Substitution | replacing a variable with a number or another expression in an algebraic expression |
| Subtraction Property of Equality | the property that states that if you subtract the same number from both sides of an equation, the new equation will have the same solution |
| Term | the parts of an expression that are added or subtracted |
| Variable | a symbol used to represent a quantity that can change |
