Answer:
The coordinates of the images are P' (-4, -1), Q' (2, -1), R' (2, -4)
Step-by-step explanation:
If the point (x, y) is translated horizontally h units and vertically k units, then its image is (x + h, y + k) and the rule of translation is T (x + h, y + k)
∵ The vertices of the polygons are P (-5, 4), Q (1, 4), R (1, 1)
∵ The rule of translation is (x, y) → (x + 1, y - 5)
→ That means add each x-coordinate by 1 and subtract each
y-coordinate by 5
∴ P' = (-5 + 1, 4 - 5)
∴ P' = (-4, -1)
∴ Q' = (1 + 1, 4 - 5)
∴ Q' = (2, -1)
∴ R' = (1 + 1, 1 - 5)
∴ R' = (2, -4)
∴ The coordinates of the images are P' (-4, -1), Q' (2, -1), R' (2, -4)
