Fiest we need to find the slope of the line: \n" ); document.write( "-2x+3y=3 or 3y=2x+3 or y=2x/3+3/3 or y=2x/3+1 (red line)the slope of this line is 2/3. \n" ); document.write( "For a line to be perpendicular to this line it has to ahve a slope of -3/2. \n" ); document.write( "If it passes through (-6,3) then the equation is: \n" ); document.write( "3=-6(-3/2)+b where b is the y intercept. \n" ); document.write( "3=18/2+b \n" ); document.write( "3=9+b \n" ); document.write( "b=3-9 \n" ); document.write( "b=-6. \n" ); document.write( "Thus this line equation is: \n" ); document.write( "y=-3x/2-6 (green line) \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " |
