Hello from MrBillDoesMath!
Answer:
AB = (-7,5,-7)
Discussion:
The vector AB = B - A =
(-4, 7, 2) - (3, 2, 9) = => subtract component-wise
(-4 -3, 7-2, 2-9) =
(-7,5,-7)
Thank you,
MrB
The vector for the line AB is ( -7i + 5j -7k ).
A vector is a two-dimensional entity with both magnitude and direction. A vector can be visualized geometrically as a directed line segment.
Given points are A(3, 2, 9) and B(-4, 7, 2). The vector will be calculated as:-
AB = B - A = ( -4 - 3 , 7 - 2 , 2 - 9 )
AB = ( -7 , 5 , -7 )
Vector AB = -7i +5j-7k
Hence, the vector AB is (-7i +5j-7k).
