Find the parametric equation of a line that passes through the points:

A = (1, 2, 3, 4), B = (3, 4, 5, 7)

Would i do: AB = (2, 2, 2, 3)

So the answer would then be:

w = 1 + 2t

x = 2 + 2t

y = 3 + 2t

z = 4 + 3t

have i done this correctly?

I was also curious how it would even be possible to have 4 points, i didnt think it was possible to think of anything more than 3 points? (3 dimensions)

Thanks
