Plotting a 3D vector

Question

I want to plot this 3D vector using tikz3D .Since I'm new to Latex, I find this task a bit difficult. I saw a couple of similar sort of questions in this forum but their pictorial representations are a bit different to this. It would be appreciated if anybody could help me.

@manooooh I edited the question to indicate the vector equation. — SL_MathGuy, Jan 20 '20 at 06:31
@Schrödinger'scat I changed the original image by mistake. Corrected it now. Sorry about that. — SL_MathGuy, Jan 20 '20 at 06:42

Thanks. By the way, I changed the vector. Anyways, I could get an idea of how to plot it by looking at your answer – SL_MathGuy Jan 20 '20 at 06:32
How can we indicate the Y-intercept and Z-intercept? – SL_MathGuy Jan 20 '20 at 06:34

@SL_MathGuy What do you mean by that? – Jan 20 '20 at 06:38
I meant how can I indicate 2 on Y & Z axes. – SL_MathGuy Jan 20 '20 at 06:42
2

@SL_MathGuy I added them. – Jan 20 '20 at 06:51
