y-axis
Definition
The y-axis is the vertical line on a coordinate plane. It is used to measure and represent the values of the dependent variable in a graph.
Analogy
Think of the y-axis as a tall building with floors representing different values. Each floor represents a specific value, just like each point on the y-axis represents a specific value in a graph.

x-axis: The x-axis is the horizontal line on a coordinate plane. It is used to measure and represent the values of the independent variable in a graph.
Origin: The origin is the point where the x-axis and y-axis intersect on a coordinate plane. Its coordinates are (0, 0).
Coordinate Plane: A coordinate plane consists of two perpendicular lines, namely the x-axis and y-axis, that intersect at their zero points (the origin). It is used to plot points and represent relationships between variables.
