Algebra.Com's Answer #57396 by checkley75(3666)![]() ![]() ![]() You can put this solution on YOUR website! A PARALLEL LINE NEEDS TO HAVE THE SAME SLOPE. THUS THE SLOPE IS 5/2. NOW SUBSTITUTE (2,1) FOR X & Y IN THE QUADRATIC EQUATION Y=mX+b \n" ); document.write( "1=5/2*2+b \n" ); document.write( "1=5+b \n" ); document.write( "b=1-5 \n" ); document.write( "b=-4 Y INTERCEPT. \n" ); document.write( "THEREFORE THE EQUATION OF THIS PARALLEL LINE PASSING THRU (2,1) IS \n" ); document.write( "Y=5/2X-4 \n" ); document.write( " |
