Question

For J(3,7) and B(1,5), write the vector JB in component form.

Answer 1

The vector JB is:

`\vec{JB}=\vec{B}-\vec{J}=(1-3,5-7)=(-2,-2)`

The component form is to write a vector in the form:

`ai+bj\text{ }`

Where the vector is (a, b).

We know the vector JB is (-2, -2), thus, in component form:

`-2i-2j`
