"The" vertical line is wrong; there are lots of vertical lines on a coordinate plane. In the usual x-y coordinate system, such a line has an equation of the form:x = a (for some constant "a"); for example: x = 3
it is called the Cartesian Coordinate Plane
Graphing a line on the coordinate plane is the two-dimensional equivalent to marking a point on a number line. It just means to graph your line with respect to the x and y axes.
The horizontal line in the Cartesian plane is called the x-axis or x-coordinate.
