Question A 06 

The figure below shows plotted against as the bestfit line through the data points. Which of the following expressions for corresponds to that bestfit line? 
Make sure you understand the problem fully: What is the question asking you to do? Are there specific conditions or constraints that you should take note of? How will you know if your answer is correct from your work only? Can you rephrase the question in your own words in a way that makes sense to you? 
If you are stuck, check the hint below. Consider it for a while. Does it give you a new idea on how to approach the problem? If so, try it! 
Hint 

What do the slope and intercept in a log plot represent? 
Checking a solution serves two purposes: helping you if, after having used the hint, you still are stuck on the problem; or if you have solved the problem and would like to check your work.

Please rate my easiness! It's quick and helps everyone guide their studies. From the graph we observe the yintercept of the line is and suppose the slope of the line is k. Then we can write down the equation of the line But notice the yaxis is , then we have
where the only possible answer is (d).
