Answer 1

The written form of vector AB in component form is; (4,8)

Vectors in component form

From the given points;

• The magnitude of vector AB is given as;

• AB = √((-1-(-9))² + (6-2)²

• AB = √80 = 4√5

From evaluation, the angle direction of AB is;

Hence, the x and y components of vector AB are;

• AB(x) = 4√5 × (1/√5) = 4

• AB(y) = 4√5 × (2/√5) = 8.
