Plotted on the horizontal axis is distance in miles to differentcities, the vertical axis is price of flight of the flight to thesecities

a. looking at the scatter plot, how is the cost of the tripassociated with the distance of the trip

b. use a straight edge to approximate a line of best fit to thedata

c. on a scale of 0 to 1 estimate how well the line fits thedata. 0= no fit 1= perfect fit. How did we choose the value of 0 or1

d. Find the equation based on your best fitline.  HINT:  To find theestimated equation, pick two points on the line and pluginto    Show your work.   Write yourequation in the form,

e

.Now, let’s calculate the least-squares line basedon your data.  Show yourwork.  You can use the following table to assist you oryou may use Excel if you are more comfortable with the software.Write your equation in the form, .
