What is the origin of a coordinate grid?

The highest point on the grid
The point where x=0 and y=0
The point at which two parallel lines meet
The endpoint of a line segment

The correct answer is: The point where x=0 and y=0

The origin of a coordinate grid is defined as the point where both the x-coordinate and the y-coordinate are zero, which is represented as (0, 0). This point serves as the reference for measuring distances and locations in the grid. In a two-dimensional Cartesian coordinate system, the horizontal axis represents the x-values, while the vertical axis represents the y-values. The intersection of these two axes at the point (0, 0) allows for establishing a reference frame from which all other points are plotted. Understanding the concept of the origin is fundamental in mathematics as it provides a starting point for graphing functions, analyzing geometric shapes, and solving equations in coordinate geometry. This foundational knowledge is essential for students as they progress through more complex mathematical concepts.
