Hello JohnBlazeSorry, but you must have misunderstood the question. The one you have asked doesn't make sense. The equation

represents a straight line passing through the point with position vector , parallel to the vector . By varying the values of , you can create the position vector of any point on the line. E.g.

- If , you get the original point itself

- If , you get the point

- If , you get the point

... and so on.

Similarly, represents, for different values of , all the points on a line passing through parallel to .

Can you see why what you've put here is meaningless? Would you like to look at the question again, and if you can't see how to do it, to post the original question here?
