Answer:
x + y = 6 (or choice C, see comment)
Step-by-step explanation:
The equation of the line through point B and perpendicular to AB can be written as ...
(Bx -Ax)(x -Bx) +(By -Ay)(y -By) = 0 . . . . where A = (Ax, Ay) and B = (Bx, By)
(2 -(-3))(x -2) +(4 -(-1))(y -4) = 0
5x +5y -30 = 0
x + y = 6 . . . . . . reduce to standard form

<em>Additional comment</em>
None of the offered choices describes a line through point B. (See second attachment). We note that several of the lines go through the point (4, 4). The segment joining points (-3, -1) and (4, 4) will be perpendicular to the line -7x -5y = -48, answer choice C.
