Answer:
(x - 1, y) -> (x - 1, y - 10)
Explanation:
Given
Translation: 1 unit left and 10 units down
Required
Determine the coordinates of the new pentagon
When a point (x,y) is translated b units left, the image of the translation is:
(x,y) -> (x - b, y)
So, 1 unit left means:
(x,y) -> (x - 1, y)
When a point (x,y) is translated h units down, the image of the translation is:
(x,y) -> (x, y - h)
So, 10 unit down means:
(x - 1, y) -> (x - 1, y - 10)
Hence, the rule of the translation is: (x - 1, y) -> (x - 1, y - 10)
