This is what you want to find:

This is what you need to do:

Predict the temperature at2,133.6 m:

The data can be written as ordered pairs (elevation, temperature). The ordered pairs for these data are (304.8, 30), (609.6, 25), (914.4, 20), (1,219.2, 15), (1,828.8, 5).

Predict the temperature at an elevation of 2,133.6 m.

Graph the data by plotting elevation on the x-axis and temperature on the /-axis.

Extend the graph line to predict the temperature at 2,133.6 m.

Practice Problems

1. Temperatures on another mountain are 33°C at sea level, 31°C at 125 m, 29°C at 250 m. and 26°C at 425 m. Graph the data and predict the temperature at 550 m.

2. Predict what the temperature would be at 375 m.
