Question 768455:  if I am graphing a system of linear inequalities how would I solve then graph 
y<2x+4 
y>2x

You can  put this solution on YOUR website! y<2x+4
 
generate values for x and y to plot
 
the equality
 
x=0,y=4 (0,4) 
x=1,y=5 (1,6) 
x=-1,y=2 (-1,2)
 
 
 
The inequality
 
Y is <  something so shade the portion below the line 
 
 
 
 
y>2x 
x=1,y=2 (1,2) 
x=2,y=4 (2,4) 
x=0,y=0 (0,0)
 
The equality 
 
 
 
y>  something so shade the portion above the line 
shade the line above
 
The inequality 
 
 
 
Merge the two plots
