WebSo let me give myself some space for the three different intervals. Now this first interval is from, not including -9, and I have this open circle here. Not a closed in circle. So not including -9 but x being greater than -9 and all the way up to and including -5. I could write that as -9 is less than x, less than or equal to -5.
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.
