René Descartes Invented the X And Y Axis (Cartesian coordinate system)
The X And Y Axis was in the 17th century.
An x-y axis, also known as a cartesian coordinate system or a coordinate plane, is a two-dimensional plane of points defined uniquely by a pair of coordinates. What does that mean? Every point on the plane is represented by two numbers, known as its coordinates. Those coordinates measure the distance of the point from the x-axis and the y-axis.
