Answer: The first one is 10. The second one is 7.
Step-by-step explanation:
1.) Find both Y points, since the X points are the same.
1a.) Find the absolute value of -3. |-3| = 3
1b.) Add the numbers together. *Do this because one is negative and the other is positive*. 3 + 7 = 10
2.) This time find both X points since the Y points are the same.
2a.) Find the absolute value of both numbers. |-9| = 9 and |-2| = 2
2b.) Now subtract 2 from 9 to get 7. 9 - 2 = 7
