Term | Definition |
Absolute Value Function | Function that has an algebraic expression in absolute value symbols. |
Dependent Variable | Variable that depends on another |
Direct Variation | Relationship between 2 variables that can be expressed by an equation in which one variable is equal to a constant times the other. |
Domain | Set of x-xoordinates |
Function | When every element is paired with exactly one element of the range |
Function Notation | Indicates that an equation is a function. |
Independent Variable | Variable that do not rely on another variable |
Linear Equation | Equation between two variables that gives a straight line when it's on a graph. |
Linear Function | Linear map. |
Linear Inequality | Inequality which involves a linear function |
Parallel Lines | Does not share a point are said to be parallel. |

Mapping Diagram | Shows how the elements are paired. |
Parent Function | Simplest function of a family of functions. |
Point-Slope Form | Y− y1 = m(x − x1) |
Range | Difference between the lowest and highest values. |
Reflection | Geometric figure is reflected across a line. |
Relation | Relation between two sets is a collection of ordered pairs containing one object from each set. |
Scatter Plot | Graph of plotted points that show the relationship between two sets of data. |
Shrink | Plane figure is distorted vertically. |
Slope | slope of a line is a # that describes both the direction and the steepness of the line. |
Slope-Intercept Form | Y=Mx+B |
Standard Form | Ax+By=C |
Stretch | Transformation by an invariant line and a scale factor (one-way stretch) or two invariant lines and corresponding scale factors (two-way stretch). |
Transformation | Original shape of the object is called the pre-image and the final shape and position of the object is the image. |
Trend Line | Line showing the general direction that a group of points seem to be heading. |
Vertex | Where 2 points meet. |
Vertical-Line Test | Visual way to determine if a curve is a graph of a function or not. |
X-Intercept | Crosses the x-axis |
Y-Intercept | Crosses the y-axis |
