Based on the graph, the water is decreasing at a slope of -3.27. the equation of the line is y = mx+b when solving for the variable b you obtain 187.02:
Everything seems reasonable, but more detail is required.
The slope has units. What are the units of the slope and how did you reason them out?
Your value of b is reasonable, but I don't think you were given the y = m x + b equation. Unless you found this equation, you wouldn't be able to solve for b. If you did find the equation then how did you find it?
What are the units of b and what does it mean in terms of the situation?
Describe how you obtained the slope.
