Answer 1

(4, -3)

last option

Explanation:

If a point is reflected over the x-axis then (x, y) → (x, -y)

B = (4, 3)

Therefore, B' = (4, -3)

The original arrowhead is pointing south (down).

If the arrowhead is rotated 270° clockwise, then it will point to the east (right). So the solution is the last option.

Answer 2

3. If triangle ABC was reflected over the x-axis, what would be the coordinate of B'?

When you reflect over the x-axis, you will flip the sign for the y-coordinate. If you reflect over the y-axis, you will flip the sign for the x-coordinate.

In this case, you are reflecting point B (4 , 3) over the x-axis, which will flip the x-coordinate sign to B' (-4 , 3)

D) (-4 , 3)

2. Rotate this figure 270 degrees clockwise

Clock-wise mean you are rotating turning right. 180° is half way, and so it will be D), as 180° is the 3rd option, and then a extra 90° will become D).
