Which of these best represents the rate of change of the temperature with
respect to altitude?

the answer is -6.5

Step-by-step explanation:

answer: y=4000x+14000

step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
