We are given equation of total campsite charge

where
C is total campsite charge C (in dollars)
d is the number of days that the site is rented
so, here we will have
C is y-axis or dependent variable
d is x-axis or independent variable
we can find any two points and then we locate it
after that we can join them to get our graph
At d=0:


so, our point is (0,8)
At C=0:



so, our point is 
now, we can locate these points and then join it
I used scatter plot graph in the insert graph function of excel and added a trend line that shows the equation of the line of best fit and the r.
The line that can be applied in this function is linear with an equation of y = 3800.6x - 5223.6 and the regression is r² = 0.8925. The y intercept represents when the starting point of a line starts. It is a strong correlation since the value of r² that is equal to 0.8925 is close to 1. We can solve the value of the investment after 6 years using the equation above.
y = 3800.6x - 5223.6
y = 3800.6(6) - 5223.6
y = 17,580
Answer:
slope is -1 and y-intercept is -9
