I've been revisiting GCSE Vectors topic and I've come across a term called "scalar multiplies" according to my book this proves that two vectors are parallel to each other. It's not very clear and doesn't give an example of what a "scalar multiply" actually is. if someone could shine some light on this it would be much appreciated.

The vector 6a+2b is a multiple of 3a+b, it is 2(3a+b). 6a+2b is therefore parallel to 3a+b.

ah, thanks. that's really helpful. but does the multiply have to be a whole number?

i understand that scalar multiples are used again. but if a vector is a scalar multiple of another wouldn't this mean that the two are parallel? how does this relate to proving that the vectors lie in a straight line.
