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

Function | A relationship in which for each input there is one output |

Domain | The set of all input (x) values for a function |

Range | The set of all output (y) values for a function |

Slope | A ratio that shows how steep or flat a line is |

Linear Equation | A function whose graph is a straight line because of a constant rate of change |

y-intercept | The point where the graph intersects the y-axis |

x-intercept | The point where a graph intersects the x-axis |

slope-intercept form | One of the ways to write a linear equation |

proportional | Each output (y) is determined by multiplying the input (x) by a constant number. The graph is a line that goes through the origin |

sum | The result of adding two or more numbers |

difference | The result of subtracting two numbers |

product | The result of multiplying two or more numbers |

quotient | The result of dividing two numbers |

order of operations | The specific order to do operations when simplifying an expression: 1. Grouping symbols, 2. Exponents, 3. Multiplication or Division (L to R) 4. Add or Subtract (L to R) |

variable | A symbol (usually a letter in the alphabet) used to represent one or more numbers |

expression | A collection of variables and numbers connected by addition, subtraction. multiplication, and/or division |

equation | A mathematical sentence in which two expressions are equal to each other |

coefficient | A number that multiplies a variable |

polynomial | An expression written as the sum or difference of terms in one variable with whole number exponents |

binomial | A polynomial that is made up of two terms |

monomial | A polynomial that has one single term |

trinomial | A polynomial that is made up of three terms |

distributive property | A way to simplify expressions |

perimeter | Total distance around a geometric shape |

area | Number of square units needed to cover geometrical shape |

complementary angles | Two angles whose sum is 90* |

supplementary angles | Two angles whose sum is 180* |

symmetry | When a shape looks exactly the same after a flip, turn, or slide |

Rigid transformation | Moving a geometrical shape without changing size or shape |

translation | Slides a shape to a new location |

rotation | Turn all points in a shape the same number of degrees around a given point |

reflection | Flips a shape over a line to create a mirror image of the shape |

least-squares regression line | Line of best fit for data on a scatterplot |

residual | Difference between a predicted value and the actual value |

correlation coefficient | A measure of how scattered data is around the line of best fit |

lurking variable | A hidden factor that explains the true cause of an association |

scatterplot | A graph displaying two-variable data the x- and y-axis |

independent variable | Changes in this quantity are not a result of changes in the other variable |

dependent variable | Changes in this quantity are a result of changes in the other variable |

outlier | A data value that is not within the normal pattern of the data |

arithmetic sequence | A number pattern that increases or decreases by a constant value ie: 3,6,9,12... |

geometric sequence | A number pattern that multiplies by te same value each time ie: 4,8,16,32... |

common ratio | The constant multiplier for a given sequence |

common difference | The constant increase or decrease in a given sequence |

recursive equation | An equation used to generate the next term in a sequence ie: t(n+1)=t(n)+m |

explicit equation | An equation used to determine any term in a sequence based on the term number ie: t(n)=mn+t(0) |
