Answer 2

Finding the Coordinates of Vectors AC and BA

To find the coordinates of vectors AC and BA, we need the coordinates of points A, C, and B. The given coordinates are A(1, -2), C(5, -2), and B(3, 6).

The coordinates of vector AC can be found by subtracting the coordinates of point A from the coordinates of point C. Similarly, the coordinates of vector BA can be found by subtracting the coordinates of point B from the coordinates of point A.

Let's calculate the coordinates of vectors AC and BA:

Coordinates of vector AC: AC = (x_C - x_A, y_C - y_A) AC = (5 - 1, -2 - (-2)) AC = (4, 0)

Coordinates of vector BA: BA = (x_A - x_B, y_A - y_B) BA = (1 - 3, -2 - 6) BA = (-2, -8)

Therefore, the coordinates of vector AC are (4, 0) and the coordinates of vector BA are (-2, -8).
