Answer:
Constant of proportionality is 
Equation is 
================================================
Explanation:
The general equation they give is c = rg
Solving for r leads to
. We divided both sides by g to get this.
Now pick any point on the diagonal line. I'll pick (3,10)
The graph shows the horizontal axis is g and the vertical axis is c. The point (3,10) means g = 3 and c = 10 pair up together.
Making r to be,
and the equation in the form c = rg would be

Answer:

Step-by-step explanation:
Given that:
f(x) approaches 150, and
g(x) approaches 0, with g(x) < 0,
as x approaches 3.
This means:

We need to evaluate:

Distributing the limit to numerator and denominator, we get:

The expression will result in infinity as the answer, but since, g(x) < 0, this means g(x) is approaching 0 from the negative side. As a result, the expression 150/0 will approach negative infinity as x will approach 3.
Therefore, we can conclude:
