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)

A) They are directly proportional

B) slope: 0.2; y-intercept: 2

Step-by-step explanation:

In the figure attached, the graph is shown.

A) If you imagine a trend line between the points, you will see a line with a positive slope, which means that the two variables are directly proportional, that is, as temperature increase, the number of popsicles sold also increase.

B) The line of best fit is the line that pass through points (40, 10) and (90, 20). Its slope (m) is calculated as follows:

m = (y2 - y1)/(x2 - x1) = (20 - 10)/(90 -40) = 0.2

Its y-intercept (b) calculated as follows:

y1 = m*x1 + b

10 = 0.2*40 + b

b = 10 - 0.2*40

b = 2

Line of best fit: y = 0.2*x + 2

she was supposed to add the hours(38.5) and multiply the amount of money she earned(7.50) resulting in $288.75 .

correct me if i'm wrong and if it is i'm truly sorry.
