In the following exercises, solve each system by graphing3x-y鈮�6y鈮�-12x

Short Answer

Expert verified

The darkest region represent the solution to the system of equation

Step by step solution

01

Given information 

Given the system of equations3x-y鈮�6y鈮�-12x

02

Checking the point for the system of equations

The equation 3x-y=6has intercept -6,2. Testing the point (0,0), we get

3(0)-0鈮�60-0鈮�60鈮�6which is not true

So origin is not included

03

Checking for another equation

The equation y=-12xhas intercept (0,0)Testing the point (0,0), we get

0鈮�-12(0)0鈮�0which is true

So origin is included

04

Graphing the equation

The graph of the equation is
