plz check my work..
Fine two vectors in opposite directions that are orthogonal to the vector u.
Solution:Two vectors are orthogonal if they are perpendicular.
There fore a vector v =(x,y) is orthogonal to u if
(x,y) . (1/2,-2/3) =1/2x-2/3y=0
now I have to find values of x and y that makes 0..?
I am stuck here...plz help? not getting right ans....

You have: .
As CaptainBlack pointed out, use any pair of values that satisfy the equation.
The most obvious is: .
. . An opposite vector would be: .
