The surface elevation of Lake Powell is decreasing at the rate of 77.2 feet per year.

What is the rate(slope) at which the sea is decreasing?

The rate at which the surface elevation of the Lake Powell is decreasing can be determined by calculating the slope(steepness) of the sea.

The slope can be given as:

Slope (Δm) = rise/run

Slope (Δm)  = Δy/Δx

slope (Δm)  = y₂ - y₁/x₂-x₁

slope (Δm)  = 3263.4 - 3881/2006-1998

slope (Δm)  = -617.6/8

slope (Δm)  = -77.2

Therefore, we can conclude that the surface elevation of Lake Powell is decreasing at the rate of 77.2 feet per year.
