\n" ); document.write( "let line1 be the required one
\n" ); document.write( " line2 be 5x+3y=7
\n" ); document.write( "to find the equation of line1 which passes through (2,-2)=(x1,y1) first find its slope. how?
\n" ); document.write( "look here
\n" ); document.write( "slope of line2 is -5/3
\n" ); document.write( "the two lines are perpendicular so use the following formula to find slope of line1
\n" ); document.write( " slope of line1 times slope of line2=-1
\n" ); document.write( "slope of line1=3/5
\n" ); document.write( "equation of line1: y-y1=slope(x-x1)
\n" ); document.write( "y+2=3/5(x-2)
\n" ); document.write( "5y+10=3x-6
\n" ); document.write( "3x-5y=-16 this is the required equation\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
