The scatter plot shows a hiker's elevation above sea level over time. The equation of the trend line shown is y = 8.77x + 686. To the nearest whole number, predict what the hiker's elevation will be after 2 hours and 25 minutes.

707 feet above sea level

Step-by-step explanation:

2 hours and 25 minutes is about 2.4167 hours.

Therefore:

y=8.77x+686

y=8.77(2.4167)+686

y=21.1944+686

y=707.1944

So the hiker's elevation will be approximately 707 feet above sea level
