Point# B (-1.6,-2.1)#

Explanation:

#x-3y = 5# Eqn (1)

#3y = x - 5#

#y = x/3 - 5/3#

Slope #m = 1/3#

Slope of perpendicular line = -1/m = -3#

Equation of AB is
#y - -3 = -3 (x - -1)#

#y + 3x = -6# Eqn (2)
Solving Eqns (1), (2)

#10x = -13, x = -1.3#

#y = -2.1#
Mid point (-1.3,-2.1)

Point B (-1.6, -1.2)
