Answer:
Option B, -1/2
Step-by-step explanation:
The slope is change in y over change in x.
Since this line is facing downward, we already know that the slope is negative.
To find the ratio, find the change in y and divide the change in x.
Change in y = -1
Change in x = 2
Change in y over change in x: -1/2
Answer: Option B, -1/2
