Question | Answer |
Addition Property of Equality | The property that states that if you add the same number to both sides of an equation, the new equation with have the same solution. |
Algebraic Expression | An expression that contains at least one variable. |
Algebraic Inequality | An inequality that contains at least one variable. |
Coefficient | The number that is multiplied by the variable in an algebraic expression. |
Constant | A value that does not change |
Coordinate Plane | A plane formed by the intersection of a horizontal number line called the x-axis and a vertical number line called the y-axis. |
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. |
Equivalent Expressions | Algebraic expressions that have the same value for every value of variable. |
Evaluate | To find the value of a numerical or algebraic expression. |
Graph of an Equation | A graph of the set of ordered pairs that are solution of the equation. |
Inequality | A mathematical sentence that shows the relationship between quantities that are not equivalent. |
Inverse Operations | Operations that undo each other: addition and subtraction, or multiplication and division. |
Isolate the Variable | To get a variable alone on one side of an equation or inequality in order to solve the equation or inequality. |
Like Term | Two or more terms that have the same variable raised to the same power. |
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. |
Ordered Pair | A pair of numbers that can be used to locate a point on a coordinate plane. |
Origin | The point where the x-axis and y-axis intersect on the coordinate plane. |
Simplify | To write a fraction or expression in simplest form. |
Solution of an Equation | A value or values that make an equation true. |
Solution of an Inequality | A value or values that make an inequality true. |
Solution Set | The set of values that make a statement true. |
Solve | To find an answer or a solution. |
Substitute | To replace 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. |
X-axis | The horizontal axis on a coordinate plane. |
X-coordinate | The first number in an ordinate pair; it tells the distance to move right or left from the origin. |
Y-axis | The vertical axis on a coordinate plane. |
Y-coordinate | The second number in an ordinate pair; it tells the distance to move up or down from the origin. |
