The y-axis is one of the two perpendicular lines that make up the Cartesian coordinate system, along with the x-axis. It is a vertical line that extends infinitely in both the positive and negative directions.
The y-axis is used to measure and represent the vertical or up-down position of points in a coordinate plane. It is labeled with positive numbers above the origin (0,0) and negative numbers below the origin. The origin is the point where the x-axis and y-axis intersect, which is typically at the center of the coordinate plane.
Each point in the coordinate plane is identified by its x and y coordinates. The y-coordinate represents the vertical position of the point, while the x-coordinate represents the horizontal position. The position of a point on the y-axis is determined by its distance from the origin, with points above the origin having positive y-coordinates and points below the origin having negative y-coordinates.
The y-axis is often used in mathematics to visualize and solve equations, graph functions, and represent relationships between variables. It is an essential tool for understanding and working with coordinate geometry and algebraic concepts.
