Scientists are studying the temperature on a distant planet. They find that the surface temperature at one location is

25

°

Celsius. They also find that the temperature decreases by

3

°

Celsius for each kilometer you go up from the surface.

Let

T

represent the temperature (in Celsius), and let

H

be the height above the surface (in kilometers). Write an equation relating

T

to

H

, and then graph your equation using the axes below.
