(-4,7) answer A
if u reflect it over y axis
Given:
Two vectors are:


To find:
The projection of u onto v.
Solution:
Magnitude of a vector
is:

Dot product of two vector
and
is:

Formula for projection of u onto v is:




On further simplification, we get



Therefore, the projection of u onto v is
