For this question, we compute the slope of each line. To compute the slope of the lines we use the following formula:


m=(y_1-y_2)/(x_1-x_2)

Line AB:


m_(AB)=(7-6)/(-4+2)=(1)/(-2)=-(1)/(2)

Line CD:


m_(CD)=(-2-3)/(2+8)=(-5)/(10)=-(1)/(2)

Therefore we conclude that lines AB and CD are parallel.
