Answer: The lines WX and YZ are parallel.
Step-by-step explanation: We are given to check whether the lines WX and YZ are parallel, perpendicular or neither if the co-ordinates of the endpoints of both the lines are
W(3,4), X(5,7), Y(8,2) and Z(6,-1).
We know that the slope of a straight line passing through the points (a, b) and (c, d) is given by
![m=(d-b)/(c-a).](https://img.qammunity.org/2020/formulas/mathematics/middle-school/l994x5mgafn1iyxedhlpex60fr6oq9126v.png)
So, the slope of the line WX is
![m_1=(7-4)/(5-3)=(3)/(2)](https://img.qammunity.org/2020/formulas/mathematics/college/a12ugwe1jpok1seyfwn2bm0kgazlux33h4.png)
and the slope of line YZ is
![m_2=(-1-2)/(6-8)=(-3)/(-2)=(3)/(2).](https://img.qammunity.org/2020/formulas/mathematics/college/b5hywfi84u88umiuxarqxxqsjhunp37ylu.png)
Since, we get
so the two lines WX and YZ are parallel.
Thus, the lines WX and YZ are parallel.
