### Transcript of Graphing inequalities

1. 1. Graphing inequalities THAT INVOLVE VERTICAL & HORIZONTAL LINES
2. 2. If you have x = number, you are graphing a vertical line where all the x values on the line are equal to that number. This is the graph of x=2
3. 3. Then if you have x number or x number, you are graphing the line first and then shading where the inequality states. This is the graph of x 2 (Shaded the xs greater than 2)
4. 4. If you have y = number, you are graphing a horizontal line where all the y values on the line are equal to that number. This is the graph of y=0
5. 5. Then if you have y number or y number, you are graphing the line first and then shading where the inequality states. This is the graph of y 0 (Shaded the ys less than 0)
6. 6. Remember and mean you use a solid line when graphing. But > and < mean you use a dotted line when graphing.
7. 7. If your solution is the x values below -2 and the y values above 3, you would write the following system of inequalities: x < -2 graphed: y > 3
