Prove or disprove that the quadrilateral with vertices \( W(4,6), X(1,13), Y(7,13) \), and \( Z(10,5) \) is a parallelogram by finding the slopes of opposite sides. Write 'undefined' if the slope is undefined. Show your work here Hint: To add the square root symbor. \( (\sqrt{\square}) \), type "root" \( m_{W X}= \) \( m_{Z Y}= \) \( m_{W Y}= \) \( T h e ~ q u a d r i l a t e r a l \) \( m_{X Y}= \) \( Z \)
