axis | One of two perpendicular lines of a coordinate place that intersect at the origin. The plural form of axis is axes. |
coordinate plane | A plane formed by the intersection of a horizontal number line called the x-axis and a vertical number line called the y-axis. |
ordered pair | A pair of numbers that indicates a point on a coordinate plane. |
origin | The point where the x-axis and the y-axis intersect on the coordinate plane (0, 0). |
quadrant | The x- and y-axes divide the coordinate plane into four regions. These regions are called quadrants. |
x-axis | The horizontal axis of a coordinate plane. Also the horizontal axis of a bar graph or histogram. |
x-coordinate | The first number in an ordered pair, which tells the distance to the right or left from the origin when graphing in a coordinate plane. |
y-axis | The vertical axis of a coordinate plane. Also the vertical axis of a bar graph or histogram. |
y-coordinate | The second number in an ordered pair, which tells the distance to move up or down from the origin when graphing in a coordinate plane. |
