Question 978099
x<-3
Dotted line vertical on the x-axis at -3.  Shade everything to the left.  On second graph, you have to decide whether to shade above or below the line, and the line has to be dashed or dotted,not solid.  Use 0,0 to decide.  0+0<6  That is true, so the origin and everything on that side is shaded.

y>-3 is a horizontal dotted line along y=-3 and everything above is shaded.
