Question 127882
Graph the system of 
5x – 2y < 10
 x + 2y > -2
 x –  y > -4
----------------
Solve each for "Y":
y > (5/2)x - 5
y > (-1/2)x - 1
y <  x + 4
-------------------
Graph the boundary for each of these inequalities
by graphing each EQUALITY:
y = (5/2)x - 5
y = (-1/2)x - 1
y =  x +4
--------------------
{{{graph(400,300,-10,15,-10,15,(5/2)x-5,(-1/2)x-1,x+4)}}}
-------------------
Shade the half-plane above (5/2)x-5
Shade the half-plane above (-1/2)x-1
Shade the half-plane below x+4
-----------------------------
The intersection of these half-planes is the solution set for
the system of three inequalities.
