Answer:

1. The graph of linear inequalities include a dashed line if they are greater than or less than but not equal to. Linear equations, on the other hand, include a solid line in every situation. Moreover, linear inequalities include shaded regions whereas linear equations do not.

2.

Step 1: Always start by isolating the variable y on the left side of the inequality.

Step 2: Change the inequality to equality symbol. For now, you will deal with a line.

Step 3: Graph the boundary line from step 2 in the XY-XY−plane. The following are the three common methods that you can use to graph a line. It doesn’t matter which one you choose.

Step 4: The last step is to shade one side or region of the boundary line.

Step 5: Use this optional step to check or verify if you have correctly shaded the side of the boundary line.

Answer:

1. Linear inequalities include a dashed line if they are greater than or less than but not equal to. While, linear equation include a solid line in every situation.

2. Steps in Graphing Linear Inequalities

Step 1 : Solve the inequality for y.

Step 2 : Treat the inequality as a linear equation and graph the line as either a solid line or a

dashed line depending on the inequality sign.

a. If the inequality sign does not contain an equals sign (< or >) then draw the line as

a dashed line.

b. If the inequality sign does have an equals sign (≤ or ≥) then draw the line as a

solid line.

Step 3 : Shade the region that satisfies the inequality

Step 4 : Repeat steps 1 – 3 for each inequality

Step 5 : The solution set will be the overlapped region of all the inequalities.

(But for simple way "another way")

Steps in Graphing Linear Inequalities in Two Variables

Step 1: Solve the inequality for y.

Step 2: Graph the boundary line for the inequality .

Step 3: Shade the region that satisfies the inequality.

Step 4: Solve the second inequality for y.

Step 5: Graph the boundary line for the second inequality.

Step 6: Shade the region that satisfies the second inequality.

Step 7: The solution set will be the overlapped region.

3. I think you need analyze first the graph of an inequality in two variables is the set of points that represents all solutions to the inequality, which a linear inequality divides the coordinate plane into two halves by a boundary line where one half represents the solutions of the inequality. Then, boundary line is dashed for > and < and solid for ≤ and ≥.
