\( \begin{array}{l}\text { This is the point where the } x \text {-axis meets the } y \text {-axis. The } \\ \text { x-coordinate and } y \text {-coordinate are both } 0 \text {. }\end{array} \) Which attribute did Leonardo describe to his classmate? A Scale B Origin C X-axis D Y-axis

The attribute Leonardo described to his classmate is the "Origin." The origin is the point where the x-axis and y-axis intersect on a Cartesian coordinate system, and it's denoted as (0,0). This point serves as the reference for all other points in the plane, making it fundamental in understanding the layout of coordinates. The x-axis represents the horizontal line, while the y-axis stands vertically. Both axes divide the Cartesian plane into four quadrants, helping to locate points and graph equations. Understanding their roles is crucial for grasping the fundamentals of coordinate geometry, making navigation through mathematics much easier!
