C
open paren negative 1 comma 3 close paren
D
open paren negative 1 comma negative 3 close paren

Explanation

Solve the equations together: subtract −x + y = 4 from 6x + y = −3 to eliminate y, giving 7x = −7, so x = −1. Substitute into the first equation: −(−1) + y = 4, which gives y = 3. The lines intersect at (−1, 3), choice B.
