To study the relationship between the elevation and average annual precipitation in a nature preserve, rain gauges were constructed on different locations with elevation ranging from 0 to 5694 feet. After 30 years, the average annual precipitation for each location was calculated.

Statistical software was used to conduct a simple linear regression about the relationship between the average annual precipitation (in inches) and elevation (in 100 feet). The following equation for the regression line was given:

Precipitation = 25.12 + 0.8264 * Elevation

What is the interpretation of the estimated slope?

What is the interpretation of the estimated intercept?
