A system of two linear inequalities is shown here { x 4 y ≥ 10 3 x − 2 y < 12 { x 4 y ≥ 10 3 x − 2 y < 12 To solve a system of linear inequalities, we will find values of the variables that are solutions to both inequalities We solve the system by using the graphs of each inequality and show the solution as a graphFor instance, the simple inequality x ≥ 3 denotes all real numbers x that are greater than or equal to 3 As with an equation, you solve an inequality in the variable x by finding all Graph y = x2 5x 12 You can see that the graph is above the xaxis when x is less than 4 or when x isWhereas to represent the inequality Y is greater than five on a number line and on the coordinate plane so let's do the number line first let me just draw out a number line that's my number line all the possible values of Y let's make that zero on the number line we could obviously go into the negative into negative numbers but we're going to be greater than five so I'll focus on the positive

Now an inequality uses a greater than, less than symbol, and all that we have to do to graph an inequality is find the the number, '3' in this case and color in everything above or below it Just rememberGraphing Inequalities 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 lineIf the inequality is ≤ or ≥, graph the equation as a solid lineThis line divides the xy plane into two regions a region that satisfies the inequality, and a region that does not 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
Graph the inequality y < 2x 2 Step 1 Graph the inequality as you would a linear equation Think of y = 2x 2 when you create the graph Remember to determine whether the line is solid or dotted In this case, since the inequality symbol is less than (👉 Learn how to graph linear inequalities written in standard form Linear inequalities are graphed the same way as linear equations, the only difference bei7 Shade The Appropriate Region Of The Graph, Based On The Inequality Sign To shade the appropriate region, we shade above or below the curve depending on the sign of the inequality For y > f(x) > 0 or y >= f(x), we shade above the parabola curve For y < f(x) or y
