The correct answer is:
C

The number of points is equal to the number of integral solutions ( x, y ) such that .

So, x, y are integers such that satisfying the inequation . The number of selections of values of x is 7, namely –3, –2, –1, 0, 1, 2, 3. The same is true for y . So the number of ordered pairs ( x, y ) is 7×7. But (3, 3), (3, –3), (–3, 3), (–3, –3) are rejected because they do not satisfy the inequation

So the number of points is 45.
