A single number, a variable, or a coefficient-variable multiplied together | Term |

Terms with matching variables, matching exponents, and constants | Algebraic Terms |

A number that is multiplied with a variable in an algebraic term | Coefficient. Example in 4x, the coefficient is the number 4. |

A letter symbol that stands in for a number that we don't know yet in an algebraic term | Variable. Example in 4x-7 = 5, the variable is the letter x |

A number on its own (it's "constantly lonely") | Constant. Examples x + 5 = 9, the constants are 5 and 9 |

Vertical lines on a coordinate plane (graph) | No Slope/Undefined |

Horizontal lines on a coordinate plane (graph) | Zero Slope |

An equation where the graph is a line; The points on the line are the solutions to the equation. | Linear Equation |

Name the steps to graph a linear equation. | 1. Make a table of values using the equation 2. Plot the (x,y) ordered pairs 3. Draw a line through points with arrows 4. Write the original equation on the line |

Lines that intersect and form vertical angles; The angles are opposite from each other and are congruent | Vertical Angles |
