Algebra.Com's Answer #14075 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! Sounds as though you know the slope of the given line is 1/2 \n" ); document.write( "So the slope of the line perpendicular to it is -2. \n" ); document.write( "If m=-2 and the line passes through (-2,-1) you get: \n" ); document.write( "-1=(-2)(-2)+b \n" ); document.write( "b=-5 \n" ); document.write( "Equation of the line is y=-2x-5 \n" ); document.write( "Standard form is ax+by=c \n" ); document.write( "Therefore rewrite your equation as 2x+y=-5 to put it \n" ); document.write( "in standard form.\r \n" ); document.write( "\n" ); document.write( "Cheers \n" ); document.write( "Stan H. \n" ); document.write( " |
