How to verify points A,B that it has equal points To C,D

[Rabinov23]

solution] take the C-Ordinates of A,B use the formula TO FIND OUT THE SLOPE Of A,Band then compare it to the c-ordinates that you already have for CD
Am I right?, what do you think, thank you very much for any help

To re-write in a slightly different way:

take the coordinates of A,B use the formula TO FIND OUT THE SLOPE Of AB

and then use the co-ordinates of C & D TO FIND OUT THE SLOPE Of CD

take the coordinates of A & D use the formula TO FIND OUT THE SLOPE Of AD

and then use the co-ordinates of B & C TO FIND OUT THE SLOPE Of BC

That will complete (b) & (c)

What will be your strategy for answering (d)?
