Algebra.Com's Answer #675716 by 0764229590(3) You can put this solution on YOUR website! since the lines are parallel, \n" ); document.write( "therefore the gradient of the other line is also -3\r \n" ); document.write( "\n" ); document.write( ".'.y=-3x+c \n" ); document.write( "substitute the point (0;12) to solve c \n" ); document.write( ".'.12=-3(0)+c \n" ); document.write( " 12=0+c \n" ); document.write( "then c=12\r \n" ); document.write( "\n" ); document.write( "therefore y=-3x+12 \n" ); document.write( " |
