y = mx + b ==> 5 = -3m + b, and \r
\n" ); document.write( "\n" ); document.write( "4 = 5m + b\r
\n" ); document.write( "\n" ); document.write( "Multiply 5 = -3m + b by 5, to get 25 = -15m + 5b
\n" ); document.write( "Multiply 4 = 5m + b by 3 to get 12 = 15m + 3b
\n" ); document.write( "Add:\r
\n" ); document.write( "\n" ); document.write( "37 = 8b ==> b = 37/8, the y-intercept.
