How would you write a system of linear inequalities from a graph?

Step-by-step explanation:

You need to know how to write a linear equation from its graph.

A graphed system of linear inequalities will have 2 lines. Each line may be solid or dashed. In addition, there is shading on one side of each line.

For each line, do this:

First, find the equation of the line.

Second, if the line is solid, you will use >= or <= instead of the equal sign. If a line is dashed, you will use < or > instead of the equal sign.

To find out whether the sign is greater than or less than, guess one of the two signs. Then test a point on the shaded side. If the point works in the inequality, you guessed correctly. If it does not work, reverse the symbol.

Do this for each inequality.
