Answer:
Option A. (6,2)
Step-by-step explanation:
We have the following inequality:

Solving for y we have:

The line that limits the region of inequality is

Then the region of inequality are all values of y that are less than 
In other words, the points belonging to the inequality are all those that lie below the line.
To find out which point belongs to this region substitute inequality and observe if it is satisfied
A. (6,2)

<em> is satisfied</em>
B. (2, 6)

<em>it is not satisfied</em>
C. (2, -1)

it is not satisfied
<em>The answer is the option A</em>
