|dw:1361081269043:dw| Why would x=0 make $$V_a$$ zero?

It's an example in my book. $V_b-V_a=-\int_{xa}^{xb}Edx$

all i can tell you is x=0 means yz plane. |dw:1361081413415:dw|

I guess I can chose where x=0 is. The question is the following: A uniform electrostatic field points in the +x direction and has a magnitude of E=10N/C=10V/m. Find the potential as a function of x, assuming that V=0 at x=0.

oh nevermind.....LOL since x=0 it's at the yz plane...silly me haha
