graph the line. 4x+3y+9=0\r
\n" ); document.write( "\n" ); document.write( "what I have been getting.. but is incorrect...\r
\n" ); document.write( "\n" ); document.write( "3y+9=0-4x
\n" ); document.write( "3y=0-4x-3y **** don't subtract 3y from the right side. Where's the 9?
\n" ); document.write( "y=-4 over 3 x
\n" ); document.write( "===================
\n" ); document.write( "4x+3y+9=0
\n" ); document.write( "If you want to solve for y:
\n" ); document.write( "3y = -4x - 9
\n" ); document.write( "y = (-4/3)x - 3
\n" ); document.write( "------------
\n" ); document.write( "To graph it, you need 2 points.
\n" ); document.write( "Pick 2 values for x and find y.
\n" ); document.write( "I would use multiples of 3 for x to avoid fractions.
\n" ); document.write( "x = 3 --> y = -7 (3,-7)
\n" ); document.write( "x =-3 --> y = 1 (-3,1)
\n" ); document.write( "Plot the 2 points, draw a line thru them.
\n" ); document.write( " \n" ); document.write( "
\n" );
