Question

Hiking 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 = 8.23x + 667, 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. feet above sea level.

Answer 1

y = 8.23x + 667

y = 8.23(170) + 667

y = 1399.1 + 667

y = 2066.1 ft

Result

Elevation = 2066.1 ft
