Hi Candidate,

The coordinates are given by A(1,2,3) and B(2,2,4) as points in the three coordinate system. The value of AC bar is given by- x coordinate equals 2-1 equals to 1.

The value of y- coordinate equals to 2-2 equals to 0. The value of z- coordinate equals to 4-3 equals to 1. So, the value of AC bar is in coordinate form- (1,0,1).

Hope that you have got your answer!! Have a Good Day.
