Hi,

Must first sketch the lines...

1) y>-x+4  Green Line

   y≤x+2 Blue Line

Shade Area that is ≤ Blue Line AND  > than the Green Line

(area between the lines on left side ,shading to include Blue Line)



2){y<=1/2x-3 Blue Line

 y≥2/3x-3 Green Line

Shade the Appropriate Area



3) y+3≤2x 0r y ≤2x -3 Green Line

 x≤3 Blue Line

Shade Area that is ≤ of both lines
