**Consider the vector v between (-4,-4,-4) and (6,7,1).**

What vector has the same length as vector v, but points in the opposite direction?

### 1 Answer | Add Yours

The vector being described here is <10,11,5>

6-(-4)=10, 7-(-4)=11, 1-(-4)=5

To find the vector that is the same length but in the opposite direction, you take the opposite (negative) of each entry. So here, the vector you want is:

<-10,-11,-5>
