2. Graph an inequality on a number line. Inequality Statements We frequently speak of one value being greater than or less than another value. We say that ‘‘5is less than7’’ or ‘‘9is greater than4.’’ These relationships are calledinequalities. We can write inequalities in mathematic...
Inequalities are best thought of as representing different regions on a number line: <represents the region to the left of a given number, for example represents all the numbers to the left of 3 (less than 3), which in on the number line below is shown by all the numbers in the direct...
Notice again that although the last number on the number line is -9, your solution does not stop at -9. Example #3Graph x ≥ 6 Draw a shaded circle at 6 and then shade everything on the right of 6. Notice that this time, the circle is shaded because x is also equal to 6....

because each of these is less than three units from zero. The number2will work, as will−2. But4will not work, and neither will−4, because they are too far away from zero. Even3and−3won't work (though they're right on the edge), because this is a "less than" (but not...

When you're doing a graph of a solution, the square bracket notation goes with the parenthesis notation, and the closed (that is, the filled in) dot notation goes with the open dot notation.If (further on) you have an inequality where both endpoints are actual numbers (that is, where ...
