Question

The vector v has initial point P and terminal point Q. How do you write v in the form ai + bj, that is, find its position vector given P = (5, 4); Q = (7, 8)?

Answer 1

Find a and b by subtracting the x and y values for the terminal point minus the initial point ...

Explanation:

`a=7-5=2`

`b=8-4=4`

`v=2i+4j`

hope that helped
