Answer:
5/3 or 1 2/3
Explanation:
Based on the picture that you gave on the link I will tell you to divide the rise over run or the vertical/horizontal lengths.
There are two ways to get the answer:
1. 4--1/3-0=5/3
2. 5 up/ 3 horizontal =1 2/3
These two give the same solution if we are going based on the picture.
