Graph the linear inequality:

4x+2y鈮�-8

Short Answer

Expert verified

The graph is -

Step by step solution

01

Step 1. Given information 

Linear inequality:4x+2y鈮�-8

02

Step 2. Graph 

We have,

4x+2y鈮�-8

4x+2y=-8 boundary line

Now, at 0,0-

40+20鈮�-8

0鈮�-8

So, 0,0is a solution.

The graph of the linear inequality -

All points in the shaded region and on the boundary line, represent the solutions to 4x+2y鈮�-8.
