Answer:
The line y =x across which angle QPR is reflected to create Q'P'R'.
Step-by-step explanation:
We are given that a triangle PQR whose vertices are P is at (1,-4),Q at (2,-2) and R at (4,-5).
The image of triangle PQR is triangle P'Q'R' obtained after reflection.
The coordinates of P' is (-4,1).
The coordinates of Q' is (-2,2).
The coordinated of R' is (-5,4).
We have to find the line that is angle QPR reflected across to create Q'P'R'.
We can see that the transformation rule is given by
[tex](x,y)\rightarrow (y,x)[/tex]
Therefore, the reflection line y=x across which angle QPR is reflected to create Q'P'R'.
Answer:y=x
