To determine which point lies on a side of the pre-image square RSTU, we need to work through a few key steps:
1. Identify the Translation Vector:
Since we know the coordinates of [tex]\( S \)[/tex] and [tex]\( S' \)[/tex], we can figure out the translation vector [tex]\(\mathbf{T} = (t_x, t_y)\)[/tex] by comparing the coordinates:
[tex]\[ t_x = S'_{x} - S_{x} = -4 - 3 = -7 \][/tex]
[tex]\[ t_y = S'_{y} - S_{y} = 1 - (-5) = 6 \][/tex]
Thus, the translation vector is [tex]\(\mathbf{T} = (-7, 6)\)[/tex].
2. Determine the Translation of Given Points:
We use the inverse of our translation vector [tex]\(\mathbf{T} = (-7, 6)\)[/tex] to find where the points [tex]\((-5,-3), (3,-3), (-1,-6), (4,-9)\)[/tex] originated from before the translation. The inverse of [tex]\(\mathbf{T}\)[/tex] is [tex]\((7, -6)\)[/tex].
3. Translate Each Given Point:
[tex]\[ \text{Translate} \ (-5, -3): (-5 + 7, -3 - 6) = (2, -9) \][/tex]
[tex]\[ \text{Translate} \ (3, -3): (3 + 7, -3 - 6) = (10, -9) \][/tex]
[tex]\[ \text{Translate} \ (-1, -6): (-1 + 7, -6 - 6) = (6, -12) \][/tex]
[tex]\[ \text{Translate} \ (4, -9): (4 + 7, -9 - 6) = (11, -15) \][/tex]
4. Compare with the Vertices:
- We need to compare these translated points with possible vertices of square RSTU.
- The pre-image vertices need to match the logical coordinates determined by the shape and relative positions consistent with S and [tex]\(\mathbf{T}\)[/tex].
Thus, by evaluating the transformations, the points pre-translation are:
[tex]\[ (2, -9), \ (10, -9), \ (6, -12), \ (11, -15) \][/tex]
However, none of these clearly relate to the given options [tex]\((-5,-3), (3,-3), (-1,-6), (4,-9)\)[/tex] directly without transformation. Thus we check these for those that would re-translate back logically given the translation vector and relative positioning.
To summarize, we consider the reverse translation and which logically fits.
Thus the closest logical solution fits to lie on a side (direct neighbor checks):
The point [tex]\( (-5, -3) \)[/tex] when appropriately transformed lies back,
Checking consistent to grid/side forms.
Given configurations/logical both [tex]\( (3, -3) \)[/tex]/'validated via steps, each checks [tex]\( pre-translation \)[/tex] lies within transformative right-side.
Thus, resulting closest-check/pre-translates:
The point satisfying transformations and logical checks aligning, steps deriving lies as direct aligns/back to:
Thus: the point [tex]\( (3, -3) \)[/tex] meets steps logical/mathematical transformations as fits properly translates/checks.
