Get Inequalities And Numbers Lines Matching Worksheet Integers

With inequalities, you can add colored shading to your Desmos graph. Use strict inequalities (< and > ) for dotted lines and non-strict inequalities (≤ and ≥ ) for a solid line.

To plot an inequality, such as x>3, on a number line, first draw a circle over the number (e.g., 3). Then if the sign includes equal to (≥ or ≤), fill in the circle. If the sign does not include equal to (> or <), leave the circle unfilled in.

To graph linear inequalities given in standard form, convert to slope-intercept form and then determine the y-intercept and the slope. Graph 4x + 5y ≥ 15. To convert this example to slope-intercept form, first subtract 4x from both sides of the inequality. Then, divide all terms by 5.

To graph an inequality, treat the <, ≤, >, or ≥ sign as an = sign, and graph the equation. If the inequality is < or >, graph the equation as a dotted line. If the inequality is ≤ or ≥, graph the equation as a solid line.

Graph Linear Inequalities in Two Variables Identify and graph the boundary line. If the inequality is ≤ or ≥, the boundary line is solid. ... Test a point that is not on the boundary line. (If not on the boundary line, (0,0) is usually a convenient test point.) ... Shade in one side of the boundary line.

To determine if an ordered pair is a solution to a system of two inequalities, we substitute the values of the variables into each inequality. If the ordered pair makes both inequalities true, it is a solution to the system.
