How Do You Graph Inequalities On A Number Line?
Graphing inequalities on number lines is done to represent the solution to inequalities with a visual representation. It aids in visualizing the answer. Graphing inequalities is simple once a few simple processes are learned. Examples appear in parentheses. Draw a straight horizontal line. Draw arrows on both ends of the horizontal line, pointing outward. The arrows represent infinity. Draw short vertical lines at equal intervals. The number of lines, or ticks, and intervals depends on the numbers being graphed. Write the numbers in the vicinity of the number being graphed below the horizontal line, one for each tick. Figure out what the inequality solution requires. (x is equal to or greater than 1) Draw a solid dot on the number line where the number being graphed is represented. The solid dot represents the starting point for the inequality solution and it is part of the solution. Draw an arrow on the number line pointing in the direction of the inequality to infinity. Draw a line,
