In the following exercises, solve each system by graphing y鈮�-12x-3x鈮�2

Short Answer

Expert verified

The darkest region represent the solution to the system of equations

Step by step solution

01

Given information

Given the system of equationsy鈮�-12x-3x鈮�2

02

Checking the point for the equations 

The equation y=-12x-3has the intercept -3,-1.5. Testing the point (0,0), we get

0鈮�-0.5(0)-30鈮�0-30鈮�-3which is true

So origin is included

03

Checking for another equation

The equation x鈮�-2.Testing the point (0,0), we get

0鈮�-2which is not true so origin is not included

04

Sketching the graph

The graph is
