Respuesta :
I have this same problem in my 8th grade book.
(1,-1) (4,-3) (1,-5)
Then for the next problem:
J" (3,-3) K" (12,-9) L" (3, -15)
The coordinates for the final figure if rotated 90° clockwise about the origin and dilated using a scale factor of 3 is J'(-9, 3), K'(-12, 9), and L'(-3, 15)
Given the coordinate of the vertices of the figure, JKL is expressed as J(1,1), K(3,4), and L(5,1)
- If the coordinate (x, y) is rotated 90° clockwise about the origin, the resulting coordinate will be (-y, x)
- If the coordinate points J(1,1), K(3,4), and L(5,1) is rotated 90° clockwise about the origin, the resulting coordinate will be at J'(-1, 1), K'(-4, 3), and L'(-1, 5)
- To dilate by a factor of 3 means multiplying the coordinates by 3
Dilating the resulting coordinate using a scale factor of 3, the coordinates for the final figure is J'(-9, 3), K'(-12, 9), and L'(-3, 15)
