The scatter plot shows leanna's elevation
above sea level during a hike. the trend line passes through
the points (30, 1070) and (75, 1680). if leanna starts at
663 feet above sea level and maintains the same rate,
how far above sea level will she be after one hour?

2236.5

Step-by-step explanation:

The regression equation for predicting hiker's elevation is

y=9.06x+651.

Here x is the number of minutes.

We wish to estimate hiker's elevation after 175 minutes. For this purpose we put x=175 in the predicted regression equation.

y=9.06(175)+651

y=1585.5+651

y=2236.5

Thus, the hiker's elevation after 175 minutes is 2236.5 feet.
