Answer:

Option B.

Explanation:

From the given graph it is clear that the related line passes through the points (0,3) and (2,4).

So, the equation of related line is

y-y_1=(y_2-y_1)/(x_2-x_1)(x-x_1)

y-3=(4-3)/(2-0)(x-0)

y-3=(1)/(2)x

Add 3 on both sides, we get

y=(1)/(2)x+3

The related line is a solid line and shaded portion lies below the line. So, the sign of inequality must be ≤.

$y\leq (1)/(2)x+3$

Therefore, the correct option is B.
