# What is a coordinate graph?

A coordinate graph is a visual method of showing the relationship between a pair of numbers. This relationship is shown on a grid of coordinates composed of horizontal and vertical lines.

Continue ReadingA coordinate grid consists of two lines called axes, which are perpendicular. The horizontal line is the x-axis and the vertical is the y-axis.The point where the x- and y-axes intersect is called the origin. These axes are labeled like number lines, and when paired these numbers make up points called ordered pairs, which are located on the graph. Ordered pairs follow the format (x,y). For example, the point (5,8) indicates that this point is located five units along the horizontal, or x-axis, and eight units up the vertical, or y-axis.
