B
open paren negative 8 comma 2 close paren
C
open paren 8 comma 10 close paren
D
open paren 8 comma negative 10 close paren

Explanation

Set the two expressions for y equal: ½x + 6 = −¾x − 4. Adding ¾x to both sides and subtracting 6 gives 1¼x = −10, so x = −8. Substituting into y = ½x + 6 gives y = −4 + 6 = 2. The solution is (−8, 2), choice B.
