The graph of an inequality in two variables is the set of points that represents all solutions to the inequality. A linear inequality divides the coordinate plane into two halves by a boundary line where one half represents the solutions of the inequality. The boundary line is dashed for > and < and solid for ≤ and ≥.

Solve a System of Linear Inequalities by Graphing Graph the first inequality. Graph the boundary line. ... On the same grid, graph the second inequality. Graph the boundary line. ... The solution is the region where the shading overlaps. Check by choosing a test point.

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.

This negative 3 is considered our boundary. Point so we find negative three over here.

We draw a solid line (not dashed) because we're dealing with an "or equal to" inequality. The solid line indicates that points on the line are solutions to the inequality.

Steps to Graphing Inequalities: Step 1 Change the inequality symbol to "=". Graph the equation. ... Step 2 Test a point that is not on the line to check whether it is a solution of the inequality. Step 3 If the test point is a solution, shade its region. If the test point is not a solution, shade the other region.

An inequality can be represented graphically as a region on one side of a line. Inequalities that use < or > symbols are plotted with a dashed line to show that the line is not included in the region.

Steps on Graphing Linear Inequalities Step 1: Always start by isolating the variable y on the left side of the inequality. Step 2: Change the inequality to equality symbol. ... Step 3: Graph the boundary line from step 2 in the X Y − XY- XY−plane. ... Step 4: The last step is to shade one side or region of the boundary line.
