The notation "(x, y)" represents a point in a two-dimensional coordinate system, commonly used in mathematics and graphing. Here, "x" indicates the horizontal position, while "y" denotes the vertical position. Together, these values help locate a specific point on a graph or grid. In this system, the first value "x" is measured along the x-axis, and the second value "y" is measured along the y-axis. For example, the point (3, 4) means you move 3 units to the right on the x-axis and 4 units up on the y-axis.
