Axis (plural-axes): a reference line from which distances or angles are measured in a coordinate grid.
Bar Graph: a graph that uses the height or length of rectangles to compare data.
Coordinate Grid: a two-dimensional system in which the coordinates of a point are its distances from two intersection, usually perpendicular, straight lines called axes (also known as coordinate plane or coordinate system).
Coordinate System: a two-dimensional system in which the coordinates of a point are its distances from two intersection, usually perpendicular, straight lines called axes (also known as coordinate grid or coordinate plane).
Coordinates: an ordered pair of numbers that identify a point on a coordinate plane.
Corresponding Terms: terms that are in the same position in a sequence of numbers.
Data: information, especially numerical information. Usually organized for analysis.
Fraction: a way to describe a part of a whole or a part of a group by using equal parts.
Intersect: to meet or cross.
Interval: the distance between the values on the scale of a graph.
Line Graph: a graph used to show how data changes over time with points connected by line segments.
Line Plot: a diagram showing frequency of data on a number line.
Number Line: a diagram that represents numbers as points on a line.
Ordered Pair: a pair of numbers that gives the coordinates of a point on a grid in this order (horizontal coordinate, vertical coordinate).
Origin: the intersection of the x- and y- axes in a coordinate plane, described by the ordered pair (0,0).
Perpendicular: forming right angles.
Plane: a flat surface that extends infinitely in all directions.
Quadrant: a section of a coordinate grid that is separated by the x-axis and y-axis.
Scale: a series of numbers at regular intervals that help label a graph.
Sequence: a set of numbers arranged in a special order or pattern.
Unit Fraction: a fraction that has 1 as its numerator. A unit fraction names 1 equal part of a whole.
x-axis: the horizontal axis in a coordinate plane.
x-coordinate: in an ordered pair, the value that is always written first.
Example: (7,2) 7 represents the x- coordinate.
y-axis: the vertical axis in a coordinate plane.
y-coordinate: in an ordered pair, the value that is always written second.
Example: (7,2) 7 represents the x- coordinate.
