The first number in an ordered pair represents the x-coordinate, so you replace each number (-1, 2, 1) into x:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "y(-1) = 5(-1) -1 = -6\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "y(2) = 5(2) - 1 = 9\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "y(1) = 5(1) - 1 = 4\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The graph should look something like this:\r
