2x-y<=2
-y<=-2x+2
y>=-2x/-1+2/-1 ( note the < sign changes to a > sign when dividing by a negative value.
y>=2x-2
+graph%28+300%2C+200%2C+-6%2C+5%2C+-10%2C+10%2C+2x+%2B2%29+ (graph 300x200 pixels, x from -6 to 5, y from -10 to 10, 2x +2).
The > indicates that the all values (x,y) above the line are solutions.
Proof:
Let x=-4 & y=5
2*-4-(-5)<2
-8+5<2
-3<2 TRUE.
Let x=4 & y=5
2*4-5<2
8-5<2
3<2 FALSE.
