Rectangle EFGH is translated according to the rule [tex]\(T_{-5,9}(x, y)\)[/tex]. If the coordinates of the pre-image of point [tex]\(H\)[/tex] are [tex]\((-2, 3)\)[/tex], what are the coordinates of [tex]\(H\)[/tex]?

A. [tex]\((7, -8)\)[/tex]

B. [tex]\((-7, 6)\)[/tex]

C. [tex]\((3, -12)\)[/tex]

D. [tex]\((2, 1)\)[/tex]



Answer :

To determine the coordinates of the point [tex]\(H\)[/tex] after it undergoes the translation given by the rule [tex]\(T_{-5,9}(x, y)\)[/tex], we can follow these steps:

1. Identify the original coordinates of point [tex]\(H\)[/tex]:
The pre-image of point [tex]\(H\)[/tex] is given as [tex]\((-2, 3)\)[/tex].

2. Understand the translation rule [tex]\(T_{-5,9}\)[/tex]:
This translation rule means we need to move the point [tex]\(-5\)[/tex] units in the horizontal direction (left) and [tex]\(9\)[/tex] units in the vertical direction (up).

3. Apply the translation to the x-coordinate:
- The original [tex]\(x\)[/tex]-coordinate of [tex]\(H\)[/tex] is [tex]\(-2\)[/tex].
- According to the rule [tex]\(T_{-5,9}\)[/tex], we need to subtract [tex]\(5\)[/tex] from the [tex]\(x\)[/tex]-coordinate: [tex]\(-2 - 5 = -7\)[/tex].

4. Apply the translation to the y-coordinate:
- The original [tex]\(y\)[/tex]-coordinate of [tex]\(H\)[/tex] is [tex]\(3\)[/tex].
- According to the rule [tex]\(T_{-5,9}\)[/tex], we need to add [tex]\(9\)[/tex] to the [tex]\(y\)[/tex]-coordinate: [tex]\(3 + 9 = 12\)[/tex].

5. Combine the new coordinates:
After translation, the coordinates of point [tex]\(H\)[/tex] will be [tex]\((-7, 12)\)[/tex].

Hence, the new coordinates of point [tex]\(H\)[/tex] after the translation are [tex]\((-7, 12)\)[/tex], but none of the given options [tex]\((7, -8)\)[/tex], [tex]\((-7, 6)\)[/tex], [tex]\((3, -12)\)[/tex], [tex]\((2, 1)\)[/tex] match the result of the translation.

Therefore, there appears to be a mistake in the provided answer choices. The correct coordinates should be [tex]\((-7, 12)\)[/tex], but this is not listed among the provided options.
