Physics 2 (E&M) homework problem

Hey, I was just wondering if anyone on here who's good at Physics 2 could help me out. I'm studying for a test over electric fields, Gauss's law, and electric potential and I'm stuck on a problem that I think is supposed to be Gauss but I'm not sure. Here's the problem:

"An infinitely long line charge that has a uniform linear charge density equal to -1.50 micro-Coulombs/m lies parallel to the y-axis at x = -2.00m . A positive point charge that has a magnitude equal to 1.30 micro-Coulombs is located at x = 1.00m, y = 2.00m. Find the electric field at x = 2.00m, y = 1.50m."

I started out by finding the distance from the point charge to the point of reference and then calculating the field due to the point charge but I don't know what to do with the line charge. Do I use a Gaussian surface (cylinder) to find the field on the reference point, or do I just use Coulomb's law because I don't have to find the electric field everywhere?
