Question 664185
Graphing an inequality starts by graphing the corresponding straight line.  After graphing the line, there are only two additional steps to remember.


Choose a point {{{not}}} (usualy we choose a point (0,0) on the line and see if it makes the inequality true.  If the inequality is true, you will shade THAT side of the line -- thus shading OVER the point.  If it is false, you will shade the OTHER side of the line -- not shading OVER the point.

If the inequality is LESS THAN OR EQUAL TO or GREATER THAN OR EQUAL TO, the line is drawn as a solid line.  If the inequality is simply LESS THAN or GREATER THAN, the line is drawn as a dashed line.
