Algebra.Com's Answer #284584 by sofiyac(983) You can put this solution on YOUR website! OK step one: find slope of given function, which means put it in slope intercept form, so y=mx+b, so solve for y. \n" ); document.write( "2x+3y=7 subtract 2x from each side \n" ); document.write( "3y=-2x+7 divide both sides by 3 \n" ); document.write( "y=-2x/3+7/3 so slope for this line is m=-2/3 \n" ); document.write( "However, our line is perpendicular to this one, so the slope for OUR line is m=3/2 (opposite sign and flip it) \n" ); document.write( "Now we use the point given and this slope and plug it into the point slope formula, which is \n" ); document.write( "y-y1=m(x-x1) where (x1,y1) is the given point so (-3,5) \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "For standard form just subtract 3x/2 from each side \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " |
