Question

Part A: In your own words, describe the relationship between the temperature of the city and the sale of sweaters in the city. (5 points)

Part B: 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 slope and y-intercept. (5 points)


For a I got Part a


The relationship is how when temperatures are rising the sweaters sold go down but when its colder the sweater sales go up.


and for b I don't know but I do know that the line of best fit goes well in points 12,0 (15,4) (7,10)

if you could just find the slope and y intercept and show your work

Answer 1

See below.

Explanation:

The line of best fit is in the screenshot.

(12,4) and (7,9) are the selected points.

9-4=5

7-12=-5

5/-5, or -1.

The approximate slope and y-intercept is -1 and 15.
