Lines that are perpendicular to one
\n" ); document.write( "another have slopes that multiply
\n" ); document.write( "together to give -1
\n" ); document.write( "m1 * m2 = -1
\n" ); document.write( "y = -4/3x-4 has a slope of -4/3
\n" ); document.write( "-4/3 * m2 = -1
\n" ); document.write( "m2 = 3/4.
\n" ); document.write( "Using the slope 3/4 and the coordinates (-5,6)
\n" ); document.write( "y = mx + c
\n" ); document.write( "6 = 3/4(-5) + c
\n" ); document.write( "6 = -15/4 + c
\n" ); document.write( "c = 6 + 15/4
\n" ); document.write( "c = 39/4
\n" ); document.write( "Equation is:
\n" ); document.write( "y = 3/4x + 39/4
\n" ); document.write( "OR multiply through by 4
\n" ); document.write( "4y = 3x + 39.
\n" ); document.write( "Hope this helps.
