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

The x-coordinate of point A’ will be -3

Transformation process

The rule for the 180 degrees clockwise rotation about the origin is expressed as:

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

Note that both coordinates were negated, Hence the point ()3, 2)  point rotated 180° clockwise about the origin will give the coordinate (-3,-2)

The x-coordinate of point A’ will be -3
