WebDecide if it needs an open circle or a closed circle; < or > would need an open circle \leq or \geq would need a closed circle. Indicate the solution set with a straight line to the left hand side or right hand side of the number or with a straight line between the circles. E.g. Represent x < 3 on a number line. An open circle needs to be ... WebBecause the inequality is "greater than or equal to" the solution can equal the endpoint. That is why the circle is filled in. With interval notation brackets, a square bracket means it can equal the endpoint. circle filled in squared end bracket Remember---these mean the same thing---just two different notations.

What do … WebThe numbers that are less than -1 are -2,-3,-4, etc., so the arrow will point down to the left. Here is a summary of how to graph inequalities: 1) Draw a number line. 2) Put either an open circle or a closed dot above the number given. For ≤ and ≥ , use a closed dot to indicate the number itself is part of the solution. WebWhen we graph an inequality on a number line we use open and closed circles to represent the number. The open circle means the number is not included in the solution . X>5 means that whatever value x has, it must be greater than 5. The open dot shows that 5 is not a solution. Numbers greater than 5 are to the right of 5 on the number line. notice and wonder worksheet
