Question 768455: if I am graphing a system of linear inequalities how would I solve then graph
y<2x+4
y>2x
Answer by mananth(16946)   (Show Source):
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
