Answer:
(0 , 0) , (18 , 0) , (18 , -18) , (0 , -18) ⇒ the second answer
Step-by-step explanation:
∵ The vertices of the rectangles are:
(0 , 0) , (0 , 6) , (6 , 6) , (6 , 0)
∵ 3 × × R
∴ That is mean The rectangle rotate 270° around the origin
(270° anti-clockwise or 90° clockwise)
and enlargement by scale factor 3
Given:
Triangle ABC with vertices A (-1, 4), B( -4, 1), and C(-1, 1) is reflected across the y-axis and then translated 4 units to the left to form triangle A’B’C’.
To find:
The coordinates of the vertices of triangle A’B’C’.
Solution:
If triangle ABC reflected across y-axis, then
Coordinates of image after reflection across y-axis are
Then triangle translated 4 units to the left to form triangle A’B’C’.
Therefore, the vertices of triangle A’B’C’ are A’ (-3, 4), B’ (0, 1), C’ (-3, 1).
Hence, the correct option is B.
