An easy way to remember the order of operations is that we read from left to right, so the first line is the horizontal line or the x-axis, which also comes first alphabetically. The horizontal line here is referred to the x-axis and values that come first in ordered pairs are plotted along this line while the vertical line is known as the y-axis, where the second number of ordered pairs is plotted. Simply put, though, the Cartesian plane is really just two number lines where one is vertical and the other horizontal and both form right angles with one another. Points on the cartesian plane are called "ordered pairs," which become extremely important when illustrating the solution to equations with more than one data point. Cartesian planes are formed by two perpendicular number lines intersect. The Cartesian plane is named after the mathematician Rene Descartes who originally came up with the concept. Together they form squares of the same dimensions within a given map. One series of lines runs from east to west and the other from north to south. The Cartesian Plane is sometimes referred to as the x-y plane or the coordinate plane and is used to plot data pairs on a two-line graph. Correct option is B) A grid is a network of a series of vertical and horizontal lines constructed perpendicular to each other.
