When you cross two number lines that are perpendicular to each other and intersect at 0 you get?

When you cross two number lines that are perpendicular to each other at the origin (0), you create a coordinate plane, specifically the Cartesian plane. The horizontal number line represents the x-axis, while the vertical number line represents the y-axis. This setup allows for the representation of points in two-dimensional space using ordered pairs (x, y). Each point's position can be described in relation to the origin, enhancing the ability to visualize and analyze mathematical relationships.
