Graphing Inequality Rules On A Number Line. Finally draw a line going from the circle in the direction of the numbers that make the inequality true. 3 pick a number greater than 3 like 4 o if your answer is x.
Sketch a number line and draw an open circle around that number. Write x 23 in words. Sign has a solution set which is all the real numbers except a single point.
Thus to graph an inequality with a.
Step 2 Check one point that is obviously in a particular half-plane of that line to. An inequality with a. Fill in the circle if and only if the variable can also equal that number. Or leave the circle unfilled in.
