Answer:
The required graph is shown below:
Explanation:
Consider the provided information.
The company paid for these costs and made combined profits of $80 million after 4 years while profits increased $60 million per year.
Let x represents the number of years and y represents the profits.
Thus the points and slope are: (4,80) and m = 60,
The slope intercept form is:

where m is the slope of the line and c is the y intercept
Substitute, x=4, y=80 and m=60 in above formula and find the y intercept.



Hence, y intercept is negative $160 million.
Substitute m=60 and c=-160 in slope intercept form.
The required equation is:

Find x intercept by substituting y=0 in




x intercept is approximately 2.7 years.
