Want a Challenge? It was estimated that the Pittsburgh metropolitan area would have a population of 2,377,800 people at the end of 1993. Its population was expected to increase at the rate of 10 people per day. The metropolitan area of Tampa Bay was estimated to have a population of 2,067,000 at the end of 1993. Its population was expected to increase at the rate of 130 people per day. Assume there are 365 days in a year.

The equation for Pittsburgh is 2,377,800 + 10x

The equation for Tampa is 2,067,000 + 130x

In how many days will the population of the two metropolitan areas were or will be equal?

Ted and meg have each drawn a line on the scatter plot shown below: the graph shows numbers from 0 to 10 on x and y axes at increments of 1. dots are made at the ordered pairs 1, 8 and 2, 7.5 and 3, 6 and 4, 5.5 and 4.5, 4.8 and 5, 4 and 6, 3.5 and 7, 3 and 8, 1.9 and 9, 1.2 and 10, 0. a straight line labeled line p joins the ordered pairs 0, 8.5 and 10.1, 0. a straight line labeled line r joins the ordered pairs 0, 8.5 and 7.8, 0. which line best represents the line of best fit? line p, because it is closest to most data points line p, because it shows a positive association line r, because it is closest to most data points line r, because it shows a negative association
