Vocab Word | Definition |
---|---|
Quadrants | The 4 regions into which the coordinate plane is divided by the x-axis and the y-axis |
Coordinate Plane | The plane containing the x and y axes |
X-Axis | The horizontal number line |
Y-Axis | The vertical number line |
Axes | Two perpendicular number lines that are used to locate points on a coordinate plane |
Origin | The point of intersection of the two axes in the coordinate plane |
X-Coordinate | The first number in an ordered pair |
Y-Coordinate | The second number in an ordered pair |
Graph | To draw, or plot, the points named by certain numbers or ordered pairs on a number line or coordinate plane, respectively |
Relation | Any pairing of a set of inputs with a set of outputs |
Domain | The set of all inputs in a function |
Range | The set of all outputs in a function |
Mapping | Pairs one element in the domain with one element in the range |
Independent variables | The input variable of a function |
Dependent variables | The output variable of a function |
Linear equation | An equation whose graph is a line |
Function | A pairing of inputs with outputs such that each input is paired with exactly one output |
Vertical line test | If any vertical line passes through no more than one point of the graph of a relation |
Functional notation | A way to name a function using the symbol f(x) instead of y |
Linear Inequality in Two Variables | An inequality that is the result of replacing the = sign in a linear equation with less than, less than or equal to, greater than, or greater than or equal to |
Graph of an inequality in two variables | The set of points in a coordinate plane that represents all solutions of the equation |
Half-Plane | In a coordinate plane, the region on either side of a boundary line |
Boundary | A line that separates the coordinate plane into half-planes |
