#m_12=-10#

#m_34=-10#

Hence, the lines are parallel

#(x_1,y_1)-=(0,6)#

#(x_2,y_2)-=(3,-24)#

Slope
#m_12=(y_2-y_1)/(x_2-x_1)=(-24-6)/(3-0)=-30/3=-10#

#(x_3,y_3)-=(-1,19)#

#(x_4,y_4)-=(8,-71)#

Slope
#m_34=(y_4-y_3)/(x_4-x_3)=(-71-19)/(8-(-1))=-90/9=-10#

#m_12=-10#

#m_34=-10#

Hence, the lines are parallel
