Enter your answer as a number, like this: 42

Answer 1

-2

Explanation:

1. Identify two points with integer (not fraction or decimal) coordinates:

Ex: (0,5) and (3,-1)

2. subtract the y-coordinates: -1-5 = -6

and the x- coordinates (IN THE SAME ORDER): 3-0 = 3

3. divide the difference in y (-6) by the difference in x (3): -6/3 = -2
