I'll provide a visual for what I'm referring to.
*[illustration Screenshot_121.png]
A = (5, 12)
B = (2, 7)
C = (6, 1)
D = (9, 6)
The movement from B to A is "up 5, right 3"
The movement from C to D is also "up 5, right 3"
Both lines have a slope of 5/3, which tells us segment AB is parallel to segment CD.
Use the slope formula to confirm that slopeBC = slopeAD, which will show BC is parallel to AD.


Please let me know if you have further questions.
