The numbers are 8,000 to 20,000 on the Y Axis (which is the population) and 1970-2005 on the X Axis (which is the year). I'm asked to find the population of 2 cities (which are the 2 lines) on the graph using their slopes in the years 2015, 2024, and 1965. I've figured out that the slope of one line is 160. Where do I go from there? </SPAN>\n" );
