Algebra.Com's Answer #34259 by checkley71(8403)![]() ![]() ![]() You can put this solution on YOUR website! FIRST YOU NEED TO FIND THE LINE EQUATION FOR 3X-Y=-3 WHICH IS -Y=-3X-3 OR\r \n" ); document.write( "\n" ); document.write( "Y=3X+3 THIS GIVE YOU THE SLOPE OF THIS EQUATION AS -3 & THE Y INTERCEPT OF 3 \r \n" ); document.write( "\n" ); document.write( "THUS THE PERPENDICULAR LINE RUNNING THROUGH (2,-1) HAS A SLOPE OF -1/3 \r \n" ); document.write( "\n" ); document.write( "-1=-1/3*2+B THEN -1=-2/3+B OR -1+2/3=B OR B=-1/3 \n" ); document.write( "THUS THE EQUATION FOR THE LINE THROUGH (2,-1) AND PERPENDICULAR TO 3X-Y=-3 IS Y=-1/3X-1/3 \n" ); document.write( " |
