Round the​ y-intercept to the nearest​ integer.) Part 2 ​(b) Graph the data and the regression line in the same viewing window using the parameters given below the graph choices. Choose the correct graph below. A. A coordinate system has a horizontal x-axis labeled from 1980 to 2010 in increments of 1 and a vertical y-axis labeled from 0 to 30000 in increments of 5000. The following points are plotted: (1985, 5500); (1990, 9500); (1995, 12500); (2000, 16000); (2008, 25000). A line rises from left to right and passes through the points (1980, 3500) and (2010, 29000). All points appear below the line. All coordinates are approximate. B. A coordinate system has a horizontal x-axis labeled from 1980 to 2010 in increments of 1 and a vertical y-axis labeled from 0 to 30000 in increments of 5000. The following points are plotted: (1985, 5500); (1990, 9500); (1995, 12500); (2000, 16000); (2008, 25000). A line rises from left to right and passes through the points (1983, 0) and (2010, 23000). All points appear above the line. All coordinates are approximate. C. A coordinate system has a horizontal x-axis labeled from 1980 to 2010 in increments of 1 and a vertical y-axis labeled from 0 to 30000 in increments of 5000. The following points are plotted: (1985, 5500); (1990, 9500); (1995, 12500); (2000, 16000); (2008, 25000). A line rises from left to right and passes through the points (1987, 500) and (2010, 20000). All points appear above the line. All coordinates are approximate. D. A coordinate system has a horizontal x-axis labeled from 1980 to 2010 in increments of 1 and a vertica
