Answer
Since each charge is $-q$, which is a negative charge, each electric field is directed toward the charge producing it.
Work Step by Step
We can write the general equation for the magnitude of an electric field:
$E = \frac{\vert q \vert}{4\pi ~\epsilon_0~r^2}$
Note that an electric field points toward a negative charge.
Since each charge is $-q$, which is a negative charge, each electric field is directed toward the charge producing it.
