Find the number of integral

[stevecowall]

Question: Find the number of integral solutions to the inequality

x² + y²< and = 9

Solution: The possible numbers I found is 0, 1, 2, 3. So, the number of integral solutions is 4. I hope I got it right!

You need to think in terms of ordered pairs; you need to specify both x and y to state a solution.

(0,0) (0,1) (0,2) (0,3) for example. Can you think of others?
