The Coordinate Plane
Done By: Mohamad Kermani
First of all, what is the coordinate plane ?
A coordinate plane is a two-dimensional number line where the vertical line is called the Y-axis and the horizontal is called the X-axis. These lines are perpendicular and intersect at their zero points. This point is called the origin. The axes divide the plane into four quadrants.
Second, when was the coordinate plane invented ?
It was invented by Rene Descartes in the seventeenth century. Legend places this mathematical innovation within the childhood of Descartes, all on account of a fly on the ceiling. He was laying in his bed one night gazing at the ceiling sleepless watching flies crawl across the tiles when he realized that he would describe exactly where these flies were using the intersecting tiles. He is credited for this idea, and it is often called the Cartesian coordinate system!
Third, what do you do with the coordinate plane ?
You can figure out points when they are already plotted and how to plot points in various ways including graphing using intercepts and graphing using linear equations.
Who uses this stuff in their jobs ?
