Line L contains the points (2,3) and (p,q). If q = 2, which of the following could be the equation of line m, which is perpendicular to line L?

(A) 2x + y = px + 7

(B) 2x + y = –px

(C) x + 2y = px + 7

(D) y – 7 = x ÷ (p – 2)

(E) 2x + y = 7 – px

Should be A, but i'm not sure. What do you think?
