Question

Vertex B of trapezoid ABCD has coordinates (7, −2). If trapezoid ABCD is translated 3 units left, what are the coordinates of vertex Bʹ?

Answer 1

The correct answer to this question is (4,-2).

Vertex B of trapezoid ABCD has coordinates (7, −2). It is said that the trapezoid is translated 3 units left. That means that the trapezoid is moved 3 points to the left (at x axis). So 7-3 = 4. This means that the new coordinate of vertex B is (4,-2)
