Meg plotted the graph below to show the relationship between the temperature of her city and the number of people at a swimming pool: Part A: In your own words, describe the relationship between the temperature of the city and the number of people at the swimming pool. (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)

From the given data above, I used a scatter plot to present my graph using microsoft excel and added a trend line to get the line of best fit. The equation that I got is y = 2.3775x + 1.1011 and the r² = 0.8922.

Part A: The temperature of the city is directly proportional with the number of people at the swimming pool because it showed an r² = 0.8922. Also, the line is linear with first degree.

Part B: You can make a line of best fit by:

1. Plot your data in a graphing paper or excel.

2. Make sure that your plotted data has a solid mark to indicate the points in the graph.

3. Divide your data points by labeling x at the center, at the farthest part of your line (left or right diagonally).

4. If you feel that the data are now finely divided, then construct a line base on the x marks you're placing

5. Then you will notice how far or near your date points are by simply looking at the points near the constructed line that you created.

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
