Jack plotted the graph below to show the relationship between the temperature of his city and the number of ice cream cones he sold daily:

part a: in your own words, describe the relationship between the temperature of the city and the number of ice cream cones sold. (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)

Part A: When the temperature increases, the number of ice cream cones sold increases.  It shows close to a linear relationship.

Part B: y = 2x+5

Step-by-step explanation:

Part A: When the temperature increases, the number of ice cream cones sold increases.  It shows close to a linear relationship.

Part B: To write the line of best fit, use the points that run a line through the data.

You can connect (0,5) and (25,55) and have a line through the middle of the data.

This line intercepts the y-axis at (0,5) so b=5.

It's slope is

The slope is 2 and b=5 so y = 2x + 5.

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
