Vocab WordDefinition
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
