Question

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:

Part A: Describe the relationship between the temperature of the city and the number of cups of lemonade 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

See below.

Explanation:

Part A: The higher the temperature in the city, the number of lemonades sold increases.

Part B: The line of best fit is a line that will have the same amount of point on each side so you should draw a straight line and then make sure it has the same amount of point on each side. To calculate the slope use Y^2-Y^1/X^2-X^1.

The equation(rounded) would be y=0.28x-5.65
