The sign is incomplete so I will outline the rules for shading:
First, make y the subject of the formula. Then,
If the sign of y _ bx + c is:
≥ then you form a solid line and shade above it
≤ then you form a solid line and shade below it
> then you form a dotted line and shade above it
< then you form a dotted line and shade below it
