In the following exercises, solve each system by graphing.

y<2x-1y鈮�-12x+4

Short Answer

Expert verified

The darkest region represent the solution to the system of equations and the graph is

Step by step solution

01

Given information 

Given the system of equations y<2x-1y鈮�-12x+4

02

Graph the system of equations 

The equationy=2x-1has intercepts as -1,12. Testing the point 0,0, we get

0<0-10<-1which is not true so origin is not included

03

Checking for another equation 

The equation y=-12x+4has intercept 4,8. Testing the point (0,0), we get

0鈮�0+40鈮�4which is true so origin is included

04

Graphing the equation 

The graph of the equation is
