You can put this solution on YOUR website!
If the line is running parallel then we know that the values of x and y will be in relation to each other, but the integer will be different.\r
\n" ); document.write( "\n" ); document.write( "So we need to find how much this difference is.\r
\n" ); document.write( "\n" ); document.write( "We can do this by substituting y and x into the known equation and then we can solve the variable.\r
\n" ); document.write( "\n" ); document.write( "Let us call the variable z\r
\n" ); document.write( "\n" ); document.write( "So y = 9x + z
\n" ); document.write( "16 = 9(11) + z
\n" ); document.write( "16 = 99 + z
\n" ); document.write( "16 - 99 = z\r
\n" ); document.write( "\n" ); document.write( "so z = -83\r
\n" ); document.write( "\n" ); document.write( "Therefore the formula for the line will be:\r
\n" ); document.write( "\n" ); document.write( "y = 9x - 83\r
\n" ); document.write( "\n" ); document.write( "to check substitute value of x into the formula (11 )and y should be equal to 16:\r
\n" ); document.write( "\n" ); document.write( "y = 9(11) -83
\n" ); document.write( "y = 99 - 83
\n" ); document.write( "y = 16!!! \n" ); document.write( "

\n" );
