Question

Point A is at (-7,5) and is rotated 180 degrees about (0,0). What are the coordinates of A after the rotation?

A) (-7, -5)
B) (7, -5)
C) (7, 5)
D) (-7, 5)

Answer 1

Rotating point A at (-7,5) 180 degrees around the origin results in the point having coordinates (7, -5).

Step-by-step explanation:

When point A at coordinates (-7,5) is rotated 180 degrees about the origin (0,0), each coordinate is negated to get the new position of the rotated point. Specifically, the x-coordinate -7 becomes 7, and the y-coordinate 5 becomes -5. Therefore, the coordinates of point A after the rotation are (7, -5).
