EDIT: I copied the problem wrong
Line thru (-3,-5) and (6,1) in standard form.
Point point form for the line joining (a,b) and (c,d) is
(c-a)(y-b) = (d-b)(x-a)
(6 - -3)(y - -5) = (1 - -5)(x - - 3)
9(y + 5) = 6(x + 3)
9y + 45 = 6x + 18
27 = 6x - 9y
2x - 3y = 9
Ax + By = C
That satisfies the constraints,
A=2, B=-3, C=9
A+B+C=8
Answer: 8
Check: 2x - 3y = 9 thru (-3,-5) and (6,1)
2(-3)-3(-5)= -6 + 15 = 9 good
2(6) - 3(1) =12 - 3 = 9, good
