Answer:
y = 3x - 1
Step-by-step explanation
We manipulate the scatter plot feature in Ms. Excel then we simply add the linear trend line displaying the equation on the chart.
The excel output is attached below.
The relation exhibited by the data set is y = 3x - 1; given the value of x, the value of y is obtained by multiplying x by 3 and subtracting 1 from the result.

Solution: The regression equation is:
Where x is the number of years since it opened in 2003.
We have to find the cost of a vehicle to drive through the safari in 2008.
Therefore using the given equation, we have:
Therefore, the best estimate for the cost of a vehicle to drive through the safari in 2008 is $8.42.
Hence the option C.$8.42 is correct
The first row represents the input. The second row represents the value that the function f assumes for each input above. The third row represents the value that the function g assumes for each input above.
To compute f(1), we look for 1 in the first row (third column) and we look for the correspondent value for f. In this case, we have f(1)=4
Similarly, we look for 3 in the first row (last column) and we look for the value of g. In this case, we have g(3)=3.
Now we can plug the values in the formula:
