Final answer:
The slope of the line that represents the relationship between cost and clicks is 0.14.
Step-by-step explanation:
The cost C, in dollars, for advertising on MySpace is proportional to the number of n of clicks on the advertisement.
We can represent this relationship using a linear equation of the form C = k * n, where k is the constant of proportionality.
Given that a business is charged $35 for 250 clicks on its advertisements, we can use this information to find the value of k.
Dividing the cost by the number of clicks, we get 35/250 = k.
Therefore, the slope of the line that represents the relationship between cost and clicks is k = 0.14.
