Question 669690:  How to shade the solution set to the system of a inequalities.
 
 
x+2y>-2 
3x+y<3 
 Answer by jim_thompson5910(35256)      (Show Source): 
You can  put this solution on YOUR website! First solve for y in each equation and get into slope intercept form
 
 
x+2y>-2
 
 
2y > -x-2
 
 
y > -(1/2)x-2/2
 
 
y > -(1/2)x-1
 
 
-------------------------------
 
 
3x+y < 3
 
 
y < - 3x + 3
 
 
======================================
 
 
So after solving for y, we get 
 
 
y > -(1/2)x-1 
y < - 3x + 3
 
 
Now graph the inequalities separately
 
 
To graph the inequality y > -(1/2)x-1, first graph the line y = -(1/2)x-1.
 
 
Make this line a dashed line.
 
 
Then shade above the dashed line.

Make this line a dashed line.
 
 
Then shade below the dashed line.
 
 
The final solution region will be the overlapping portion of the two individual shaded regions
