Y-Axis
The y-axis is one of the two perpendicular lines on a coordinate plane, with the other line being the x-axis
The y-axis is one of the two perpendicular lines on a coordinate plane, with the other line being the x-axis. It is usually drawn vertically and intersects the origin, which is the point (0,0), at its bottom. The y-axis represents the vertical or up-and-down direction in a coordinate system.
The points on the y-axis are defined using their y-coordinate, which is the distance of each point from the origin along the y-axis. Points above the origin will have positive y-coordinates, while points below will have negative y-coordinates.
The y-axis is commonly used to represent the dependent variable in a graph, where the independent variable is represented on the x-axis. It is often used to depict quantities such as time, temperature, height, or any other variable that can change vertically.
When interpreting a graph, the y-axis allows us to see how the dependent variable changes as the independent variable varies. By plotting points or connecting them with a line, we can visualize how the values on the y-axis correspond to different values on the x-axis.
In summary, the y-axis is an important component of a coordinate plane, used to represent the vertical or up-and-down direction in a graph or chart. It helps us understand how one variable changes in relation to another.
