Question

Jean transformed a point by using the rule (x, y) right-arrow (x minus 6, y + 8). The image point is (–4, 1). Which point is the pre-image?
(–10, 9)
(2, –7)
(–2, 7)
(10, –9)

Answer 1

Answer:

(2, -7)

Step-by-step explanation:

Answer 2

The pre-image is the reverse of the image, so we need to alter the rule used.

The given rule to find the image is (x minus 6, y + 8). We need to add to x and subtract from y, so the rule becomes (x + 6, y minus 8).

Add 6 to the x coordinate, and subtract 8 from the y coordinate.

-4 + 6 = 2

1 – 8 = -7

The new coordinates, or the pre-image, is (2, -7).

Answer:

B. (2, -7)
