Put both equations in the slope/intercept form for graphing
:
4x + y < 8
y < -4x + 8 (red)
and
x – y > 2
-y > -x + 2
y has to be positive, multiply by -1, this reverses the inequality sign
y < x - 2 (green)
;
:
Graph these two equation
+graph%28+300%2C+200%2C+-6%2C+5%2C+-10%2C+10%2C+-4x%2B8%2C+x-2%29+
:
Because of the inequality sign, the feasibility area is below the red line and below the green line
