The Y-axis, also known as the vertical axis, is one of the two axes used in coordinate systems to locate and describe points in a two-dimensional plane. The other axis is called the X-axis or horizontal axis.
In a Cartesian coordinate system, the Y-axis is positioned vertically, running parallel to the vertical or “up-down” direction. It intersects the X-axis at the point called the origin, which has coordinates (0,0). The positive direction of the Y-axis goes upwards and the negative direction goes downwards.
Points on the Y-axis have X-coordinates of zero, which means their position is entirely determined by the Y-coordinate. For example, a point on the Y-axis at (0,5) would be located five units above the origin.
The Y-axis is commonly used in various mathematical contexts, such as graphing functions, plotting data, and representing mathematical relationships. It allows us to understand and visually depict how the dependent variable (often represented on the Y-axis) changes with respect to the independent variable (often represented on the X-axis) in a graph.
