Yes the given vectors are orthogonal or perpendicular. For that to be true, the dot product of the vectors must be equal to 0.

To find the dot product, multiply the x values and add them to the multiplied y values.

$4*6+8*-3= 24-24=0$

The vectors are orthogonal

How do you find the inner product and state whether the vectors are perpendicular given <4,8>*<6,-3><4,8>*<6,-3>?
