(adsbygoogle = window.adsbygoogle || []).push({}); Potential --> electric field. Almost done, need a little help.

1. The problem statement, all variables and given/known data

The potential in a region between x=0 and x=6.00m is V=a+bx.

a=10[V/m]

b=-7[V/m^{2}]

Determine a) the potential at x=0, 3m, and 6m

b.) the electric field at the same locations

2. Relevant equations

3. The attempt at a solution

So I got stuck on part b. It says along x so I disregarded y and z. Partial of V with respect to x is -b which equals 7 but the units are V/m^{2}which doesn't seem right at all.

What did I screw up?
