To Graphing Linear Equations. The Coordinate Plane. The coordinate plane has 4 quadrants. Each point in the coordinate plain has an x-coordinate (the abscissa) and a y-coordinate (the ordinate). The point is stated as an ordered pair (x,y). Horizontal Axis is the X – Axis. (y = 0) Vertical Axis is the Y- Axis (x = 0) Plot the following points:
The graph of x = a is a vertical line passing through the point (a, 0) on the x-axis. To graph a vertical line, such as 4x + 12 = 0, solve the equation for x to write it in the form x = a, plot the point (a, 0) on the. x-axis, and draw a vertical line through it (see Example 5).
