First, you need to make the fractions have the same denominator:
15 1/2 ---> 15 + (1/2 x 5) = 15 5/10
2 1/10 ---> 2 1/10
Then you need to subtract them from each other:
15 5/10
<u>- 2 1/10</u> (or) 15 5/10 - 2 1/10 = 13 4/10
13 4/10
This gets the answer: <u>13 4/10</u>

Answer:
<em>(9,-5)</em>
Step-by-step explanation:
When you go down, the number will decrease. The vertical position is the Y axis. -3-2=5.
When you go right, the number will increase. The horizontal position is the X axis. 5+4=9
<em>(9,-5)</em>
