# How do you graph the inequality #-9<=2x+y#?

##### 1 Answer

Solve for

#### Explanation:

First, solve for **equality**

Solving for

We usually look at this with the

The inequality symbol is **solid line** on your graph. You can find two values by plotting points.

graph{y=-9-2x [-10, 5, -15, 5]}

Finally, you can see that the point

To determine which side to shade, plug in these values and find which one makes the inequality true and which one makes the inequality false.

For

For

**not** bigger than

Thus, we shade on the side containing the point

graph{y>=-9-2x [-10, 5, -15, 5]}
