y = 5 x + -7
\n" ); document.write( "Compare this equation with y=mx+b
\n" ); document.write( "slope m = 5
\n" ); document.write( "
\n" ); document.write( "The slope of a line perpendicular to the above line will be the negative reciprocal -1/5
\n" ); document.write( "m1*m2=-1
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "m= - 1/5 ,point ( -10 , 3 )
\n" ); document.write( "Find b by plugging the values of m & the point in
\n" ); document.write( "y=mx+b
\n" ); document.write( "3 = 2.00 + b
\n" ); document.write( "b= 1
\n" ); document.write( "m= - 1/5
\n" ); document.write( "The required equation is y =- ( 1/ 5)x + 1
