A(1, 1) refers to a specific point in a two-dimensional coordinate system, where the first number represents the x-coordinate and the second number represents the y-coordinate. In this case, A(1, 1) is located one unit to the right of the origin (0, 0) and one unit up. This point can be visualized on a graph where the horizontal axis is labeled as the x-axis and the vertical axis as the y-axis. In mathematics, points like A(1, 1) are used to represent locations in a plane. They are essential in various fields, including geometry, physics, and computer graphics. Understanding how to plot and interpret points is fundamental for analyzing shapes, movements, and relationships between different objects in a coordinate system.
