Graphing two-variable linear inequalities Video transcript Write an inequality that fits the graph shown below. So first we just have to figure out the equation of this line. We can figure out its y-intercept just by looking at it.

In light of this fact, it may be easiest to find a solution set for inequalities by solving the system graphically. How To Solve Systems of Inequalities Graphically. 1) Write the inequality in slope-intercept form or in the form \(y = mx + b\). For example, if asked to solve \(x + y . Determine which ordered pair satisfies the system of linear equations, then graph both equations and show the point of intersection to the right of the problem. Be sure to label axes and provide a scale. 1. a. (1, 4) b. (2, 9) c. 2. a. (8, 13) b. (-7, 6) c. (0, 4) Solve the following systems by graphing. Systems of linear inequalities A system of linear inequalities in two variables consists of at least two linear inequalities in the same variables. The solution of a linear inequality is the ordered pair that is a solution to all inequalities in the system and the graph of the linear inequality is the graph of all solutions of the system.

We first need to review the symbols for inequalities: There are endless solutions for inequalities. In light of this fact, it may be easiest to find a solution set for inequalities by solving the system graphically.

In doing so, you can treat the inequality like an equation. This will form the "boundary" of the inequality -- on one side of the line the condition will be true, on the other side it will not. Review how to graph a line here.

Notice that it is true when y is less than or equal to. In step 3 we plotted the line the equal-to caseso now we need to account for the less-than case. Since y is less than a particular value on the low-side of the axis, we will shade the region below the line to indicate that the inequality is true for all points below the line: Plug in a point not on the line, like 0,0.

Verify that the inequality holds.

We have shaded the correct side of the line. Find all values of x and y that satisfy: Notice that this inequality is already in the slope-intercept form.

I will replace the given inequality symbol for the equal symbol to plot the line.

Now plot that line as shown: Since this is a case where the inequality is true for y values greater than or equal to something, we have shaded the area above the line. Again, select any point above the graph line to make sure that it will satisfy or reveal a TRUE statement in terms of the original inequality.

Since that point was above our line, it should be shaded, which verifies our solution. Multiple inequalities - a system of inequalities A system of inequalities has more than one inequality statement that must be satisfied.

Graphically, it means we need to do what we just did -- plot the line represented by each inequality -- and then find the region of the graph that is true for BOTH inequalities. For the two examples above, we can combine both graphs and plot the area shared by the two inequalities.

Graphing systems of inequalities. Section – Graphs of Linear Inequalities We solve these systems by graphing. To graph a system of linear inequalities, we graph each inequality (using techniques from previous examples in this section) and then find where all shaded regions intersect.

The intersection represents the solution set to the system of below, along with. Determine which ordered pair satisfies the system of linear equations, then graph both equations and show the point of intersection to the right of the problem.
