Graphing an inequality often conveys its meaning more clearly than just w*riting the inequality Rules Two rules for graphing inequalities 1 For ≥ and ≤ we use a shaded circle, , to show that we are including the number 2 For > and we use an opened circle, , to show that we are not including the number Example 2 Graph x ≤ 4 First graph the Line y = x 4 by its 2 intercepts Make x = 0, > yintercept = 4 Make y = 0 > xintercept = 4 The solution set of the inequality (1) is the area above the LineGraph Linear Inequalities in Two Variables In the following exercises, graph each linear inequality 15 Graph the linear inequality y > 2 3 x − 1 Answer 16 Graph the linear inequality y < 3 5 x 2 17 Graph the linear inequality y ≤ − 1 2 x 4

To solve your inequality using the Inequality Calculator, type in your inequality like x7>9 The inequality solver will then show you the steps to help you learn how to solve it on your ownLet's go over four (4) examples covering the different types of inequality symbols Example 1 Graph the linear inequality y > 2 x − 1 y>2x1 y > 2x − 1 The first thing is to make sure that variable y y y is by itself on the left side of the inequality symbol, which is the case in this problem Next is to graph the boundary line byX (x 4) (x 3) = 23 If we now solve the equation, we obtain Leaving the answer as x = 8 would not be a solution to the problem We are asked to "find the numbers" The answer must be We check the problem by noting that the first number (8) is four more than the second (4) and is three less than the third (11) and that their sum is 23
2 The graph of y > 3/4x 2 is a dashed line 4 One solution to the inequality is (0, 0) 5 The graph intercepts the yaxis at (0, 2)Step by step guide to graphing linear inequalities First, graph the "equals" line Choose a testing point (it can be any point on both sides of the line) Put the value of (x,y) ( x, y) of that point in the inequality If that works, that part of the line is the solution If the values don't work, then the other part of the line is the The lefthand side of the inequality 4 − x > −5 is nonnegative, so the graph of y = 4 − x must lie above or on the xaxis The graph of the righthand side of 4 − x > −5 is a horizontal line located 5 units below the xaxis Therefore, the graph of y = 4 − x always lies above the graph of y = −5
