#color(red)(D. " " 3x + 2y = -2#

Given Equation is #-2x + 3y = 12#

#3y = 2x + 12#

#y = (2/3)y + 12#

Slope of this line is #m = 2/3#

#"Slope of Line A " m_a = 2#

#"Slope of Line B " m_b = 2/3#

#"Slope of Line C " m_c = -(2/3)#

#"Slope of Line D " m_d = -(3/2)#

#"Since " m_d = - 1/ m, D " is perpendicular to the given line"#
