Answer:
b. 
Step-by-step explanation:
The given geometric series is;

The first term of this series is

The common ratio is

The sum to infinity of this series is

Substitute the given values to obtain;

This implies that;


X/y
- 8/20=42/y
- 0.4=42/y
- y=42/0.4
- y=105
The answer to this function is M = 1/9 (The slope is "M").
