Question

Point A has coordinate A(3, 2). The point is rotated 180° clockwise about the origin. What is the x-coordinate of point A’?

Answer 1

Answer:

The x coordinate is -3.

Step by Step Explanation:

180 degree rotation is (x,y) --> (-x,-y)

applying this to the coordinate A(3, 2) would be (-3, -2)

the x coordinate is -3, this is the answer.

Answer 2

Answer:

Step-by-step explanation:

A 180 degree rotation around the origin would be the same things as a reflection across the x-axis followed by a reflection across the y-axis.

This would result in the new location being (-3, -2)  The x coordinate is -3.
