complete the ordered pairs,(1,_) and (_,9) so they satisfy the equation y=-9x +18. this is what I have so far
\n" ); document.write( "y=-9x+18
\n" ); document.write( "-9(1)+18
\n" ); document.write( "y=9
\n" ); document.write( "I substituted 18 for the y and came up with 18=-9x+18 and got zero, but zero is not an option in the homework. Can anyone show me what I did wrong?
\n" ); document.write( "-------------
\n" ); document.write( "Sub as you did
\n" ); document.write( "y = -9x + 18
\n" ); document.write( "9 = -9*1 + 18
\n" ); document.write( "9 = 9 so it's correct.
\n" ); document.write( "----------------
\n" ); document.write( "For (_,9)
\n" ); document.write( "y = -9x + 18
\n" ); document.write( "9 = -9x + 18
\n" ); document.write( "x = 1
\n" ); document.write( "It's the same point. \n" ); document.write( "
\n" );
