Use the graph to help.

1. Point B ' has coordinates (-4, 2). If it was translated up to 5 units, what were the coordinates of its pre-image?

(-9, 2)
(-4, -3)
(1, 2)
(-4, 7)

Answer 1

B(-4, -3)

Step-by-step explanation:

B' (-4, 2)

• if it was translated up to 5 units, there has been change in y unit.

• in order to find its original point, we have to shift it 5 units below.

→ B = (-4, 2 - 5)

→ B = (-4, -3)
