If triangle DEF is translated 5 units down, what will be the coordinates of point E ′ in the image?

Answer:  The correct option is(B) (4, -2).Step-by-step explanation:  Given that the triangle DEF is translated  units down.We are to find the co-ordinates of point E' in the image.From the graph, we note thatthe co-ordinates of the vertices of triangle DEF are D(1, 2), E(4, 3) and F(3, 1).We know thatif a point (x, y) is translated 5 units down, then its co-ordinates becomes(x, y)  →  (x, y-5).Therefore, after translation, the co-ordinates of the vertex E' in the image areE(4, 3)  →   E'(4, 3-5) = E'(4, -2).Thus, (B) is the correct option.
