Algebra.Com's Answer #27699 by fractalier(6550)![]() ![]() You can put this solution on YOUR website! Well if the line you need is perpendicular to y=-1/3(x)+7, then its slope must be the negative reciprocal of -1/3 or 3. \n" ); document.write( "Now use the slope-interecept method \n" ); document.write( "y - y1 = m(x - x1) \n" ); document.write( "y - 6 = 3(x - 9) \n" ); document.write( "y - 6 = 3x - 27 \n" ); document.write( "y = 3x - 21 \n" ); document.write( " |
