Ответ:
I cannot see pictures, so I will explain how to find slope, so you can do it on your own.
Step-by-step explanation:
Find 2 coordinates on the line.
Ex: (2,3) and (4,6)
Subtract the y-coords and x-coords from each other and divide.
6-3 = 3
4-2 = 2
3/2
So the example slope is 3/2.
The 3 represents the rise, and 2 represents the run.
