Question

prove that the point represented by -4+3I,2-3I and -1 are collinear​

Answer 1

Answer:

You need to define “direction vector” carefully. Once you agree on a scale, you could define “direction vector” to mean a unit vector in a direction. You still have a problem, though. What do you mean by the direction of a straight line? There are two possible directions. If you define a thing called a “directed line” and “parallel” to mean in the same direction, then, yes, the unit direction vectors would be equal. The definition of a vector doesn’t include its starting point. (The starting point isn’t irrelevant, it is an extra feature and not part of the vector’s definition. Once upon-a-time, there were things called bound vectors, sliding vectors and free vectors. But that’s old fashioned. Vectors are what were called “free vectors”.)
