The y-coordinate of a point is the second number in an ordered pair. It indicates a distance along the y-axis or vertical axis in the coordinate system.
For the point (-6, 2), the y-coordinate is 2. This means that the distance along the vertical axis is 2.
For the point (3, 3), the y-coordinate is 3. The distance along the vertical axis is 3.
The y-coordinate can either be positive or negative. The y-coordinate is positive in the first and second quadrant and negative in the third and fourth quadrant.
The y-coordinate is called y-value when dealing with functions.
