# How to find the number of ways to go from on point to another on the cartesian plane ?

Supposing we have to go from (0,0) to (5,3). Then what will be the number of ways ?

Note:- You can only go up, right Please give solution with proof and logic.

Okay, so you have two choices at any given point. You can go up, and you can go right. Let's name these U and R. To get to $$(5, 3)$$, you have to make 5 R and 3 U. So all that you're really doing is computing 8 (the total number) choose 3 (or 5), which is $$\boxed{56}$$. :D · 3 years ago
