Answer:

(-3, 2)

Step-by-step explanation:

To find the coordinates of a point being reflected across the x-axis you need to use the rule (x, -y) on the point. Example: If the point was (4, 7) you would make the y value negative since it is positive, which would give you (4, -7) which is the point after being reflected across the x-axis. I know this one is for reflecting on the x-axis but for future problems if you want to reflect across the y-axis you do the same thing but with the x value, so (-x, y)

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?

lubasha [3.4K]

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:
$(x, y) = (2, -7)$
