Answer:
(x, y) ⇒ (x -2, y +2)
Step-by-step explanation:
Reflection across the line y = x+2 has the effect of interchanging x and y and translating by (-2, 2).
Reflection across the line y = x+4 has the effect of interchanging x and y and translating by (-4, 4).
The composition of these transformations is then ...
(x, y) ⇒ ((x +2) -4, (y -2) +4) = (x -2, y +2)

-15 - (-3) + 6
-15 - (-3) = -15 + 3 = 3 - 15 = - 12
-12 + 6 = 6 - 12 = -6
Your answer is -6
