Question 1092425
{{{ d^2 = ( x[2] - x[1] )^2 + ( y[2] - y[1] )^2 ) }}}
{{{ d = sqrt( ( x[2] - x[1] )^2 + ( y[2] - y[1] )^2 ) }}}
and
( x[1], y[1] ) = W( -1, 4 )
( x[2], y[2] ) = T( 4, 1 )
--------------------------------
{{{ d = sqrt( ( 4 -(-1 ) )^2 + ( 1 - 4 )^2 ) }}}
{{{ d = sqrt( 5^2 + (-3)^2 ) }}}
{{{ d = sqrt( 25 + 9 ) }}}
{{{ d = sqrt( 34 ) }}}
{{{ d = 5.831 }}}
