Triangle ABC, with A = (-2,3) B = (-4,1) and C = (-3,5), is rotated 90- clockwise about the origin to make Triangle A'B'C'. What are the y-coordinates of B'?

vertex is -B

Step-by-step explanation:

Suppose you rotate triangle ABC clockwise 90º. If ABC has vertices A (-2, 1), B (-1, 4), and C (2, 2), vertex C' is

2)

Suppose you rotate triangle ABC clockwise 90º. If ABC has vertices A (-2, 1), B (-1, 4), and C (2, 2), vertex B' is (? , 1). (Hint: Note the direction of rotation.)

3)

Use a rotation matrix to rotate figure DEFGH counterclockwise 90º. If the figure has coordinates D (1, 3), E (3, 2), F (1, -1), G (-3, -2), and H (-2, 2), the coordinates of E' are (-2, ?).

4)

Suppose you rotate triangle ABC counterclockwise 90º. If ABC has vertices A (-2, 1), B (-1, 4), and C (2, 2), vertex B' is ( ? , -1).
