Solve the given system of linear inequalities by graphing:
x+y>4
xy<7

x+y>4 will turn into y>x+4 you will graph it like it says = instead of > and shade above the line.
xy<7 will turn into y>x7. Graph like there is an = and shade above the line with a different color.
Where the colors overlap will be the answer> 
Using the following system of inequalities find the maximum value of f(x,y)=3x+2y
X>0
y>0
3x+2y<18
6x+7y<42
