Meg plotted the graph below to show the relationship between the temperature of her city and the number of people at a swimming pool: main title on the graph is swimming pool population. graph shows 0 to 30 on x axis at increments of 5 and 0 to 12 on y axis at increments of 1. the label on the x axis is temperature in degree c, and the label on the y axis is number of people at the pool. dots are made at the ordered pairs 2.5, 1 and 5, 2 and 7.5, 2 and 7.5, 3 and 7.5, 4 and 10, 5 and 10, 6 and 12.5, 6 and 15, 7 and 15, 8 and 17.5, 5 and 17.5, 7 and 20, 9 and 22.5, 7 and 22.5, 9 and 25, 11 and 27.5, 12. 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.
