Answer:

The answer to your question is y = 4 - 1.5x

Step-by-step explanation:

Data

River's speed = 2 mi/h

David's speed = 6 mi/h

Rate of change = 1.5 mi/h

From the data given, we can conclude that the rate of the boat will be the difference between David's speed and the speed of the boat = 4mi/h.

The slope must be negative because it decreases.

The only equation that satisfies both conditions is the second option.
