Proving whether function-series $f_n(x) = \frac{(-1)^nx}n$

Question

I'm asked to prove whether the following function-series on $E$ with values in $Y$ converges pointwise/uniformly/absolutely.

$$E = [-1, 1], Y= \Bbb{R}$$

$$f_n = \frac{(-1)^nx}n.$$

What I have tried so far: Using direct comparison test to find a convergent series and then using the Weierstrass M-Test but I can't find any solution to this problem.
