WebWhen solving inequalities, like, say, this one: -2x+5<25. You would cancel out the +5 with -5 and subtract 25 by 5, so you're left with this: -2x<20. But now, since you're dividing by -2 (remember that multiplying or dividing by a negative number will reverse the sign) it will no longer be less than, it will be greater than: -2x/-2>20/-2. WebMar 28, 2024 · The steps for graphing the solution set for an inequality with two variables are shown in the following example. Example 2.7.2: Graph the solution set y > − 3x + 1. Solution Step 1: Graph the boundary. Because of the strict inequality, we will graph the boundary y = − 3x + 1 using a dashed line.

WebStep 1: We need to rewrite the inequality so that it is in slope intercept form. Step 2: Graph the line. Note that the line is solid because the inequality sign is greater than or equal to. Step 3: Shade the solution set. Since y is greater than the expression, shade the side "above" the line. port authority denim shirt
