WebThe reason this happens is the absolute value always creates a positive number. And, a positive number will never = a negative number. So, let's extend that concept to inequalities. 1) An absolute value < a negative: In this situation, we have a positive value < a negative value. That would always be false.

Graphing Linear Inequalities - Math is Fun

WebTry to remember that if you divide by a negative value then the inequality flips. For example, the equation: -3x < 12 becomes x > -4 because you have divided both sides by a negative value. To check if this is correct, replace x with a value that is less than -4 such as -5. Then evaluate the original equation to see if it makes sense. WebMar 7, 2024 · To do this, turn the inequality into an equation, and graph as you would any equation of a line. [5] Plot the y-intercept, then use the slope to graph other points on the line. For example, if the inequality is , you would graph the line . The y-intercept (the point where the line crosses the y axis) is -3, and the slope is 3, or .

WebOct 6, 2024 · Two common ways of expressing solutions to an inequality are by graphing them on a number line and using interval notation. To express the solution graphically, draw a number line and shade in all the values that are solutions to the inequality. Interval notation is textual and uses specific notation as follows: Figure 2.7.1

WebSep 10, 2024 · Graph the linear inequality − 2 y − 1 > 3. We first solve the inequality. − 2 y − 1 > 3 − 2 y > 4 y < − 2 The inequality symbol reversed direction because we divided by − 2 Thus, all numbers strictly less than − 2 will satisfy the inequality and are thus solutions. Since − 2 itself is not to be included as a solution, we draw an open circle at − 2.
