To determine the new position of point P after the two translations, we’ll perform each translation step by step.

  1. Initial position: \[ P(-4, 5) \]

  2. First translation: \( (x + 3, y - 6) \) \[ P' = (-4 + 3, 5 - 6) = (-1, -1) \]

  3. Second translation: \( (x - 4, y + 2) \) \[ P'' = (-1 - 4, -1 + 2) = (-5, 1) \]

Now we have the new coordinates for point P after both transformations: \[ P''(-5, 1) \]

To determine the quadrant:

  • The x-coordinate is -5 (negative).
  • The y-coordinate is 1 (positive).

Based on these coordinates:

  • If x < 0 and y > 0, the point is in Quadrant II.

Answer to Question 1:

Quadrant II

Answer to Question 2:

To write the rule for the composition of the transformations:

  1. Combine both transformations mathematically:
    • Start with \( P(x, y) \), translate: \[ (x + 3, y - 6) \rightarrow P'(x + 3, y - 6) \]
    • Then apply the second translation: \[ P'(x + 3 - 4, y - 6 + 2) = P'(x - 1, y - 4) \]
  • The complete transformation can be expressed as: \[ (x - 1, y - 4) \]

Final answer to Question 2:

(x - 1, y - 4)
