Question

Triangle ABC with vertices A(-2, -2), B(-3, 1), and C(1, 1) is translated by (x, y) → (x - 1, y + 3). Then the image, triangle A′B′C′, is translated by (x, y) → (x + 4, y - 1), resulting in A′′B′′C′′.

a. Find the coordinates for the vertices of triangle A′′B′′C′′.

b. Write a rule for one translation that maps triangle ABC to triangle A′′B′′C′′.
