Inequality Number Line Math
The number line should now be divided into 2 regions one to the left of the point and one to the right of the point.
Inequality number line math. C solve the inequality 4t 5 11 4. Then graph the point on the number line graph it as an open circle if the original inequality was or. There is a dot on the two that is not filled in to show that it is not equal to 2. A on the number line below show the inequality 2 y 3.
The arrow going down the number line shows that x is any number smaller than 2. To solve an inequality using the number line change the inequality sign to an equal sign and solve the equation. The first inequality is x2. We just put a little dot where the 3 is right.
We can use the number line to solve inequalities containing and. Means greater than geq means greater than or equal to means less than leq means less than or equal to. Now an inequality uses a greater than less than symbol and all that we have to do to graph an inequality is find the the number 3 in this case and color in everything above or below it. Before learning about how to display inequalities on a number line you firstly need to know the following symbols and their definitions.
Write down the inequality.
