Question

Jean transformed a point by using the rule (x,y) (x-6, y+8). The image point is (–4, 1). Which point is the pre-image?

Answer 1

Answer: B, (2, -7).

Step-by-step explanation: I got the question right on the quiz.

Answer 2

For this case we have the following transformation:

`(x, y) (x-6, y + 8)`
Using the transformation we have that the image is:

`(-4, 1)`
Therefore, making use of this information, we can find the coordinates of the pre-image
We have then:

`x-6 = -4`
From here, we clear x:

`x = -4 + 6 x = 2`
On the other hand we have:

`y + 8 = 1`
From here, we clear y:

`y = 1-8 y = -7`
The coordinates of the pre-image is:

`(x, y) = (2, -7)`
Answer:
A point that is the pre-image is:

`(x, y) = (2, -7)`
