Determine the n-intercept of the graph of the car value equation V = negative 1385 n + 18,790. What is the practical significance of the n-intercept? Be sure to include units.

Question

SmokeyBrown · Answer

The equation is $$V = -1385n + 18,790$$
So, the n-intercept would be the value of "n" for which "V" is 0.
Let us try to solve for this:
0 = -1385n + 18790 ==
1385n = 18790 ==
n = 13.567
i.e. the n-intercept is 13.567

So, when "n" is equal to 13.567, the value of the car will be 0. What does "n" represent in this equation? This should allow you to answer the question of what the n-intercept practically means
