The _-coordinate is the first number in an ordered pair used to locate a point on a coordinate plane.

The x-coordinate is a crucial part of the ordered pair (x, y) that helps pinpoint the exact location of a point on the Cartesian plane. It denotes the horizontal position, indicating how far to the left or right the point is relative to the origin (0,0). So, if you ever swing by (3, 2), just remember you’re three steps over to the right and then two steps up! Now, here’s a fun fact: the Cartesian coordinate system was developed by René Descartes in the 17th century. His groundbreaking method merged algebra and geometry, allowing for the visualization of equations. So, the next time you plot a point, give a nod to Descartes for helping you navigate this mathematical landscape!
