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 |
