METHOD 1: Pick any point in the sky portion and check if it satisfies both inequalities. If it does, then shade the sky. If it does not, pick any point in the mountain portion and check if it satisfies both inequalities. If it does, then shade the mountain.

METHOD 2:

Rewrite the inequalities as "y [inequality symbol] mx + b". The inequality symbol can be either one of \lt, \gt, \leq, \geq . If both inequalities are either \lt, \text{ or } \leq then shade the mountain. If both inequalities are either \gt, \text{ or } \geq then shade the sky.

Lot of people have answered that, if the sign is < shade below and if the sign is > shade above.

**This is in not true. Follow Mahesh's suggestion**.

To see why, take the equation:

-x-y>2

Using the suggestions here, you would shade **above the line** -x-y=2

The same equation, can be re-written as:

x+y<-2

Now, you would shade **below the line**.

If it is <, you shade the mountain. If the sign is a >, you shade the sky.

You graph the inequality then dash or line the points depending if it has a line at the bottom of the greater or less sign. Now to if its a less sign you shade the mountain and its a greater sign you shade the sky.

Less than or less than/equal to signs means to shade the mountain. Greater than or greater than/equal means to shade the sky.

There will be a study set posted shortly. This will help you to understand the concept of graphing better. Promise to have a look at it, once it is posted?

If the Inequality shows this sign > then you shade the sky but if it shows this sign < then you shade the mountain.

If a line has a < symbol than you shade the mountain, is it has a > symbol you shade the sky. And if it it does not have an or equal to line under the symbol the line is dotted, if it does than the line is not dotted.

< :shade the mountain

> :shade the sky
