Solution

To solve the problem provided in the image, we need to go through two main transformations: a translation and a reflection.

Step 1: Translation

The point S(2,5)S(2, -5) is translated using the translation vector T=(13)T = \begin{pmatrix} 1 \\ 3 \end{pmatrix}.

To translate a point by a vector T=(ab)T = \begin{pmatrix} a \\ b \end{pmatrix}, you add the components of the vector to the coordinates of the point.

S(x,y)=S(x+a,y+b)S'(x', y') = S(x + a, y + b)

For the given translation: x=2+1=3x' = 2 + 1 = 3 y=5+3=2y' = -5 + 3 = -2

So, the coordinates of the point after translation are S(3,2)S'(3, -2).

Step 2: Reflection over the line x=3x = 3

Next, we reflect the translated point S(3,2)S'(3, -2) over the line x=3x = 3.

When reflecting a point (x1,y1)(x_1, y_1) over the vertical line x=cx = c, the x-coordinate changes as follows: x2=2cx1x_2 = 2c - x_1 The y-coordinate remains the same: y2=y1y_2 = y_1

For the line x=3x = 3 and the point S(3,2)S'(3, -2): x2=2(3)3=63=3x_2 = 2(3) - 3 = 6 - 3 = 3 y2=2y_2 = -2

Thus, the coordinates of the point after the reflection are (3,2)(3, -2).

Final Answer

The final coordinates of the image of point SS after the translation and reflection are (3,2)\mathbf{(3, -2)}.


Would you like more details or have any questions?

Here are five related questions for further exploration:

  1. How would the solution change if the point SS was reflected over a line such as y=2y = -2?
  2. What would the final coordinates be if the original point S(2,5)S(2, -5) was translated by a different vector, say (46)\begin{pmatrix} -4 \\ 6 \end{pmatrix}?
  3. What is the general formula for reflecting a point over a vertical line x=cx = c?
  4. How would the solution change if the reflection was over the y-axis instead of the line x=3x = 3?
  5. How do translations and reflections affect the distance of a point from the origin?

Tip: When performing multiple transformations, always follow the order given in the problem, as it can affect the final result.
