Question

Naomi plotted the graph below to show the relationship between the temperature of her city and the number of popsicles she sold daily:
Part A: In your own words, describe the relationship between the temperature of the city and the number of popsicles sold. (2 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 the slope and y-intercept. (3 points)

Answer 1

Answer:

Slope is 1/2

Step-by-step explanation:

Answer 2

There is a positive association because the number of popsicles' sold increases as the temperature increases.

The line of best fit would start at (0,2) and go straight thru to (100,22)

the slope being :
(0,2)(10,4) = (4 - 2) / (10 - 0) = 2/10 which reduces to 1/5.

The y int, where the line crosses the y axis, is (0,2)
