# Variables & Patterns

Term | Definition |
---|---|

Coefficient | The number written with the variable in any term in an expression |

Coordinate Pair | An ordered pair of numbers used to locate a point on a coordinate grid. The first number in the coordinate pair is the value for the x-coordinate and the second number is the value for the y-coordinate |

Dependent Variable | One of the two variables in a relationship. Its value DEPENDS ON or is determined by the other variable |

Equation | A rule containing variables that represents an equivalent mathematical relationship (contains an equal sign) |

Equivalent Expressions | Expressions that have the same value; represent the same quantity when the same number is substituted for the variable in each expression |

Graph | A diagram or visual representation that shows the relationship between variables |

Independent Variable | One of the two variables in a relationship. Its value DETERMINES the value of the other variable |

Inequality | A rule containing variables that represents when two values are not equal. (Greater than, less than) |

Quantity | An amount, measure or number |

Term | A number, variable, or product of a number and a variable |

Table | A list of values for two or more variables that shows the relationship between them. Often represent data made from observations, experiments, or arithmetic operations |

Variable | A symbol, usually a letter, that represents a numerical value; quantity that can change |

X-axis | The number line that is horizontal on a coordinate grid |

Y-axis | The number line that is vertical on a coordinate grid |

Algebraic Expression | A number sentence involving numbers, variables, and one or more operation signs |

Numerical Expression | A number sentence involving only numbers and one or more operation signs |
