Uniform electric field. Find the potential difference

[Bearbull24.5]

Homework Statement

Point A (2,3)m and point B (5,7)m are in a region where electric field is uniform and given by E=(4i+3j)N/C. What is potential diff Va-Vb?

Homework Equations

Not a clue

The Attempt at a Solution

I tried converting the (4i+3j) into magnitude and that is as far as I got. Not a clue what to do next

How is the electric field related to the potential?

Isnt the potential the energy required to move a charge in an electric field?
