Hi there,
\n" ); document.write( "First find the gradient of the line
\n" ); document.write( "between (2, -2) and (6,3)
\n" ); document.write( "Gradient = y(2) - y(1)/x(2) - x(1)
\n" ); document.write( "Gradient = 3 - (-2)/6 - 2
\n" ); document.write( "Gradient = 5/4
\n" ); document.write( "If two lines are parallel then they
\n" ); document.write( "have the same gradient.
\n" ); document.write( "Therefore the line containing the
\n" ); document.write( "point (-4, 18)
\n" ); document.write( "has the equation:
\n" ); document.write( "y - 18 = 5/4 (x -(-4))
\n" ); document.write( "y - 18 = 5/4(x + 4)
\n" ); document.write( "y - 18 = 5/4x + 5
\n" ); document.write( "y = 5/4x + 5 + 18
\n" ); document.write( "y = 5/4x + 23
\n" ); document.write( "OR
\n" ); document.write( "4y = 5x + 92 (Multiplied thro' by 4)
\n" ); document.write( "Hope this helps:-)
\n" ); document.write( "
\n" );
