The y-axis is one of the two perpendicular lines that form the Cartesian coordinate system, also known as the rectangular coordinate system. It is the vertical line on the coordinate plane and is used to represent the vertical or upward direction. The y-axis is usually labeled with positive values (+y) above the origin and negative values (-y) below the origin.
The y-axis is paired with the x-axis, which represents the horizontal or left-right direction. Together, these two axes create a grid system that allows us to locate points or plot graphs of mathematical functions.
In terms of coordinates, a point on the coordinate plane is written as (x, y), where x represents the position of the point along the x-axis and y represents the position of the point along the y-axis. The intersection of the x-axis and y-axis is called the origin, which is represented by the coordinates (0, 0).
The y-axis is essential in graphing functions and visualizing relationships between variables. It helps us understand how changes along the vertical direction (y-axis) affect the graph or the relationship being modeled.
