The equation should have be given as :4a-9b-5c

  • For 3 vectors to be collinear, a vector should divide the other two vectors into some ratio.

⇒4a-9b+5c=0

⇒4a=9b-5c

⇒a=(9b-5c)/4

The above equality indicates  a divides b and c  externally   in ratio 9:5.

Hence the vector points are collinear.
