👉 Ordinates are a set of numerical values that define a point in two-dimensional space. They are commonly used to describe the position of an object on a coordinate plane, particularly in mathematics and physics. Ordinates can be represented as x and y coordinates, where x is the horizontal distance from the origin (0, 0) and y is the vertical distance from the origin (0, 0). The ordinate is often used to represent a point or line on a graph. For
