When we are dealing with inequalities we have to keep in mind that the graph are regions and not figures (like lines)
The region has orientation and it is given by the sign used, if it is above something, it means the > sign, otherwise the < sign.
Now, we have a line and the region is below, so there is a < sign involved, other thing to keep in mind is that the figure can be contained in the region if is graphed using a solid line, so there is the = sign involved
