Please Help Me With This: Show That The Vectors a=5i+3j+3k, b=3i-3j+k, c=7i+8j+5k are collinear
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

They are not collinear.

The determinant of the corresponding 3x3 matrix of coefficients is not zero.
It is -4.

The determinant of the matrix %28matrix%283%2C3%2C+5%2C3%2C3%2C+3%2C-3%2C1%2C+7%2C8%2C5%29%29 is -4.
