Brainliest for the correct answer and 5 full stars
eric plotted the graph below to show the relationship between the temperature of his city and the number of cups of lemonade he sold daily:
a scatter plot is shown with the title lemonade sales. the x-axis is labeled high temperature, and the y-axis is labeled cups of lemonade sold. data points are located at 30 and 4, 40 and 6, 40 and 8, 50 and 2, 55 and 10, 65 and 14, 70 and 16, 75 and 14, 85 and 19, 90 and 20.
part a: describe the relationship between the temperature of the city and the number of cups of lemonade sold.
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.

For "Part A: Describe the relationship between the temperature of the city and the number of cups of lemonade sold."

·As the Temperature increase, the Amount of cups of lemonade also increase.

For "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."

· The Approximate line of best fit would be a linear line starting at the point (15,0), and extending out to (90,20)

To find the Approximate slope we will use the equation ΔY÷ΔX. (Y2-Y1)/(X2-X1)

with the given equation we have 20-0, which would give us ΔY, and 90-15, which would give us ΔX.

Now we have ΔY(20)/ΔX(75).

Now we do the math and 20/75 which is .266, approximately, and there for Slope=.266, and the Y-intercept would be (15,0).

I hope this helped you.

Doing this so you have two answers and a bit easier to read.

PART A:

As the temperature increases, the number of cups on lemonade sold increases.

PART B:

The line would best fit starting at (15,0) and ending at (90,20)

Slope = .226

y-intercept = (15,0)

Hope I could help some of you.
