Algebra.Com's Answer #86897 by checkley71(8403)![]() ![]() ![]() You can put this solution on YOUR website! FIRST YOU NEED TO PUT THIS EQUATION INTO THE STANDARD LINE FORMULA: \n" ); document.write( "Y=mX+b WHERE m=SLOPE & b=THE Y INTERCEPT. \n" ); document.write( "2X+3Y+5=0 \n" ); document.write( "3Y=-2X-5 \n" ); document.write( "Y=-2X/3-5/3 \n" ); document.write( " \n" ); document.write( "YOU NOW HAVE A SLOPE=(-2/3) & A Y INTERCEPT=(-5/3). \n" ); document.write( "TO FIND ANY SET OF POINTS ON THIS LINE JUST SET X=0 & SOLVE FOR Y: \n" ); document.write( "Y=-2*0-5/3 \n" ); document.write( "Y=-5/3 \n" ); document.write( "SO WE HAVE THE POINT (0,-5/3) \n" ); document.write( "YOU CAN ALSO SET Y=0 AND SOLVE FOR X: \n" ); document.write( "0=-2X/3-5/3 \n" ); document.write( "-2X/3=5/3 NOW CROSS MULTIPLY. \n" ); document.write( "-6X=15 \n" ); document.write( "X=15/-6 \n" ); document.write( "X=-5/2 \n" ); document.write( "SO WE HAVE THE POINT (-5/2,0) \n" ); document.write( " \n" ); document.write( " |
