The scatter plot shows a hiker's elevation above sea level during a hike from the base to the top of a mountain. The equation of a trend line for the hiker's elevation is y = 7.11x + 691, 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 170 minutes.
