Question

Given that P = (-7, 16) and Q = (-8, 7), find the component form and magnitude of vector QP .

<-1, -9>, square root of eighty two
<-15, 9>, square root of sixty six
<1, 9>, 82
<1, 9>, square root of eighty two

Answer 1

third choice?

Answer 2

I'd want to see your work before giving you feedback on the correctness of your choice. You're given 2 points and are asked to find vector OP connecting those points. How would you find the x-comp and the y-comp of OP? Note that the vector starts at O and ends at P.

Answer 3

QP, not OP. Sorry about that.
