Question

Jordan plotted the graph below to show the relationship between the temperature of his city and the number of cups of hot chocolate he sold daily (shown in the picture)

Describe how you can make the line of best fit. Write the approximate slope and y-intercept of the line of best fit. Show your work, including the points that you use to calculate the slope and y-intercept.

Answer 1

Answer:

I would draw a line from (40,20) to (80,8)

Step-by-step explanation:(40,2) is an outlier, so I wont use that.  I am roughly estimating that it I were to draw line from those points, It would have about the same number of dots above and below the line which tells me it is a line of best fit. Slope would be about -3 every 10 temperature climb.
