Answer 2

Answer:

C.)  f(x) = −4x + 200

Step-by-step explanation:

Since the number is decreasing, you know the slope will be negative, eliminating the first two choices. The equation in the last choice does not match the given data, so it can be eliminated.

In other words, the easiest way to solve this problem is to check the answers against the given data.

_____

If you want to write the equation from scratch, you need to find the slope. That is ...

 (change in number of cars)/(change in weeks) = (184 -192)/(4 -2) = -8/2 = -4

This matches only one answer, but you can go on to finish the equation by starting with point-slope form:

 y -192 = -4(x -2)

 y = -4x +8 +192 . . . . add 192, eliminate parentheses

 y = -4x + 200 . . . . matches choice C.)
