First simply graph the lines for y=-3 and x=6.

This equation defines a horizontal line. There is no X intercept. Y intercept is

Solved by pluggable solver: DESCRIBE a linear EQUATION: slope, intercepts, etc
this equation defines a vertical line.

  • X intercept: 6. X intercept is the intersection of the line with the x axis.

  • Y intercept: not defined (the line IS vertical)

  • Slope: not defined, can be thought of as infinite



Then since , shade the part of the graph above that line. And since , shade the part to the right of that line. Both illustrate that the numbers are getting higher along the axis. Once you have done this, you are done.
