Pick a test point, (the origin is the most convenient unless the line of the inequality falls on it), and plug it into the same linear inequality. If the test point makes the inequality true, then shade that side of the line. If the test point makes the inequality false, then shade the opposite side of the line.

Graph the system of inequalities y-2 and x3?
Graph the following Inequalities: x > 3
When graphing inequalities when do you shand upward and when do you shade downward?
Shade upward if the inequality involves a "greater than" comparison. Shade downward if the inequality involves a "less than" comparison.
which graph shows the solution to the system of linear inequalities y>2x+1 y?
3
How do you know whether to shade in the circle when putting inequalities on a number line?
If it is 'less than' or 'greater than' or 'not equal' then use an open circle.If it is 'less than or equal to' or 'greater than or equal' then use the shaded circle.
How do you solve questions that say which graph best represents the system of inequalities?
The solution to a system of inequalities is where the solutions to each of the individual inequalities intersect. When given a set of graphs look for the one which most closely represents the intersection, this one will contain the most of the solution to the the system but the least extra.
