Question

2. The graph represents the amount

Answer 1

Answer:

Slope: -3/2

With the question, we can determine that the slope with two points: (0,13.5) and (9,0). To calculate use the equation $\frac{y2-y1}{x2-x1}$ and get $\frac{0-13.5}{9-0} =\frac{-13.5}{9} =\frac{-3}{2}$

This slope means that the water is decreasing at a rate of 3/2 gallons per minute.
