Answer:
(x, y) ⇒ (x, y+6)
Step-by-step explanation:
Reflection of a value a across a point p to make b requires that a, b, and p satisfy the relation ...
p = (a+b)/2
2p = a + b
b = 2p - a
This is true for any sort of reflection. Here we have a reflection across the horizontal line y=-1, followed by a reflection across the horizontal line y=2. These reflections do not change the x-coordinate of a point, but they change the y-coordinate in accordance with the above relation.
Reflection across y = -1:
(x, y) ⇒ (x, 2(-1)-y) = (x, -2-y)
Reflection of that across y = 2:
(x, -2-y) ⇒ (x, 2(2) -(-2-y)) = (x, y+6)
The composition of the two reflections results in a translation upward of 6 units: (x, y) ⇒ (x, y+6)

Answer:
Step-by-step explanation:
(-0.5-0.5)/(3+ 3) = 1/6
y - 0.5 = 1/6(x + 3)
y - 0.5 = 1/6x + 0.5
y = 1/6x + 1
