Algebra.Com's Answer #579930 by amarjeeth123(569)![]() ![]() ![]() You can put this solution on YOUR website! Let the line be y=mx+c where m is the slope and c is the y-intercept \n" ); document.write( "y=-8/9x+c \n" ); document.write( "It passes through (5,3) \n" ); document.write( "Substituting we get, \n" ); document.write( "3=-40/9+c \n" ); document.write( "c=67/9 \n" ); document.write( "The equation of the line is 9y=-8x+67 \n" ); document.write( "8x+9y=67. \n" ); document.write( "The slope of a line perpendicular to f is 9/8. \n" ); document.write( " |
