Answer:
Given points:
- X = (2, 4)
- Y = (5, -3)
- Z = (-7, 1)
Part (a)
Rotate 90° clockwise (about the origin): (x, y) → (y, -x)
- X' = (4, -2)
- Y' = (-3, -5)
- Z' = (1, 7)
Part (b)
Dilation by a scale factor → multiply the points by the scale factor
scale factor = 2
- X'' = (8, -4)
- Y'' = (-6, -10)
- Z'' = (2, 14)
Part (c)
Reflect across the x-axis: (x, y) → (x, -y)
- X''' = (8, 4)
- Y''' = (-6, 10)
- Z''' = (2, -14)
Part (d)
Translate 2 up and 5 to the left: (x, y) → (x - 5, y + 2)
- X'''' = (3, 6)
- Y'''' = (-11, 12)
- Z'''' = (-3, -12)
