Triangle D'E'F' was formed after triangle DEF was translated 2 units to the right and 4 units up. Before the translation, what was the location of vertex E?

The answer is below

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, rotation, dilation and translation

If a point X(x, y) is translated b units up and a units right, the new location is X'(x +a, y + b).

Let us assume the coordinates of the vertex of triangle D'E'F' is at D'(-1, 5), E'(3, 2), F'(5, 8).

Since triangle DEF was translated 2 units to the right and 4 units up, the coordinate of vertex E is at E(1, -2)

if you was gonna solve for a, a is a   < -12
