Answer:

Step-by-step explanation:
We are given the following in the question:
Let the equation:

be the linear equation that represent temperature at an elevation x.
Temperature at 6000-foot level = 76 f

Temperature at 12000-foot level = 49 f

Solving the two equation, we get,

Thus, we can write the linear equation as:
