Verify that the vertices A(6.1),B(2,5),C(6,1) and D(2,4) are the vertices of a trapezoid. Does anyone know the steps to solve this? Thanks so much.

slope ab = 6/8 = 3/4
slope bc = 6/4 = 3/2
slope cd = 3/4 = 3/4
slope da = 3/8
note AB is parallel to CD 
thanks so much?
could you please tell me the formulas you used to get those answers?
