Step-by-step explanation:
<u>Column Vector</u>
Vectors are matrices having only one column or one row. A vector having only one column is called a column vector, and a vector having only one row is called a row vector.
It's required to find the vector AB as a column vector, and we are given the coordinates of A=(6,4) and B=(2,7).
The vector directed from A to B is found by subtracting its corresponding coordinates:


Now we express the vector as a one-column matrix as follows:

Answer:
13
Step-by-step explanation:
8 × 4 = 32
12 + 7 = 19
32 - 19 =13
