1. Graphing Linear Inequalities - Math is Fun

Link: https://www.mathsisfun.com/algebra/graphing-linear-inequalities.html
Description: WEBPlot y = 2x−1 (as a solid line because y≤ includes equal to ): 3. Shade the area below (because y is less than or equal to): Example: 2y − x ≤ 6. 1. We will need to rearrange this one so "y" is on its own on the left: Start with: 2y − x ≤ 6. Add x to both sides: 2y ≤ x + 6. Divide all by 2: y ≤ x/2 + 3.

Description: WEBTo graph a linear inequality: Step 1 Replace the inequality symbol with an equal sign and graph the resulting line. Step 2 Check one point that is obviously in a particular half-plane of that line to see if it is in the solution set of the inequality. Step 3 If the point chosen is in the solution set, then that entire half-plane is the solution ...

Description: WEBGoogle Classroom. We graph inequalities like we graph equations but with an extra step of shading one side of the line. This article goes over examples and gives you a chance to practice. The graph of a two-variable linear inequality looks like this: A coordinate plane with a graphed system of inequalities.

Description: WEBSep 27, 2020 · Graphing Inequalities. To graph an inequality: Graph the related boundary line. Replace the <, >, ≤ or ≥ sign in the inequality with = to find the equation of the boundary line. Identify at least one ordered pair on either side of the boundary line and substitute those \((x,y)\) values into the inequality.

Description: WEBTo Graph a Linear Inequality. Identify and graph the boundary line. If the inequality is \(≤\) or \(≥\), the boundary line is solid. If the inequality is \(<\) or \(>\), the boundary line is dashed. Test a point that is not on the boundary line. Is it a solution of the inequality? Shade in one side of the boundary line.
