Using the y = mx + b formula for a line. First fill in the forumla for the line l displayed. slope = -3/6 and y-intercept is 3.

So line l is y = (-3/6)x + 3. Now form the inequality to represent all points below that line.

An easier solution is:

If you put x = 6, only the last option gives y = 0. So, E is the answer

Eqn of line: y = mx+c

c = 3, m = -1/2

so y = -x/2 + 3

Everything point that lines below the line must be y < -x/2 +3

(a side-note: every point that lies above the line must be y > -x/2+3)
