Question

The x-coordinate of point P is positive, and the y-coordinate of point P is positive. In which quadrant is point P?

Answer 1

Use algebra tiles to find the difference. Let one white tile equal +1 and one black tile equal -1.
10 - 9

-19
19
-3
1

Answer 2

Based on the given information, point P is in the first quadrant.

Answer 3

To find the difference between 10 and 9 using algebra tiles, we can represent 10 with ten white tiles and 9 with nine white tiles. Since we are subtracting 9 from 10, we need to remove 9 white tiles. This leaves us with one white tile remaining. Therefore, the difference between 10 and 9 is 1.
