Simple Graph The Inequality On A Number Line
Solve the following linear inequality and graph.
Graph the inequality on a number line. Is graphed on this number line and written in interval notation. The dark line represents all the numbers that satisfy x 3. Integral with adjustable bounds.
There is no lower end to those numbers. For instance look at the top number line x 3. -3x 12 0.
The solution set of the given inequality is - 2. -3x 12 - 12 0 - 12. We can also graph inequalities on the number line.
To solve an inequality using the number line change the inequality sign to an equal sign and solve the equation. In chapter 4 we constructed line graphs of inequalities such as. Inequalities can also be graphed on a number line.
We write x 1. Q 3 - Graph the following inequality on the number line. Closed circles are used for numbers that are less than or equal to and.
Textless and textgreater. We found that in all such cases the graph was some portion of the number line. Since an equation in two variables gives a graph on the plane it seems reasonable to assume that an inequality in two variables would graph as some portion or region of the plane.
