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. |
