Answer:
20%
Step-by-step explanation:
To find what percentage is $10 out of $50, we divide 10 by 50:
![\frac{10}{50}=0.2](https://tex.z-dn.net/?f=%20%5Cfrac%7B10%7D%7B50%7D%3D0.2)
If we want to get the result in percentage form, we simply multiply it by 100%:
![0.2\cdot 100\%=20\%](https://tex.z-dn.net/?f=0.2%5Ccdot%20100%5C%25%3D20%5C%25)
So a tip of $10 on a $50 bill is a tip of 20%.

Graph it and you would find that (-2,2) is 3 units higher than the line y=-1. So you would reflect it across by starting at (-2,-1) and count downwards, 3 to get (-2,-4).
The answer should be (-1/3,3/4) if I did the math correct
