\n" ); document.write( "\n" ); document.write( "a)Find the slope of the line through (1995, 1,000,000) and (1998, 1,300,000) and interpret your result.\r

Points: (0, 1) and (3, 1.3)\r\n" );
document.write( "Slope, or \r\n" );
document.write( "\r\n" );
document.write( "Model: \"matrix%281%2C3%2C+y+-+y%5B1%5D%2C+%22=%22%2C+m%28x+-+x%5B1%5D%29%29\"\r\n" );
document.write( "        y - 1 = .1(x - 0) ------ Substituting (0, 1) for (x1,y1), and .1 for m\r\n" );
document.write( "        y - 1 = .1x\r\n" );
document.write( "            y = .1x + 1\r\n" );
document.write( "\r\n" );
document.write( "You need to graph this yourself!\r\n" );
document.write( "\r\n" );
document.write( "Time period from 1995 - 2022: 2022 - 1995 = 27 years\r\n" );
document.write( "Using a 27-year time period and the model, we get: y = .1(27) + 1\r\n" );
document.write( "                                                   y = 2.7 + 1 = 3.7\r\n" );
document.write( "               Estimated cost of a 2022 Superbowl ad.: $3.7 million.
You need to determine if this cost is unrealistic or realistic. \n" ); document.write( "
