The equation of a trend line for the hiker's elevation is y=8.87x+620, where x represents the number of minutes and y represents the hiker's elevation in feet. Use the equation of the trend line to estimate the hiker's elevation after 165 minutes After 165 minutes, the hiker's elevation will be about ___ feet above sea level.
