What is the image point of (-7,3) after the transformation rx-axis R180degrees

Answer 1

This is a composition of transformations

First you have to rotate 180 and next you have to reflect over x axis.

The given point (-7,3) is on the second quadrant, after 180 rotation it will be on the fourth quadrant, (7,-3) Next you have to reflect that point over the x axis. So the final image of the point is on the first quadrant, (7,3).

hope this helps!

Answer 2

R₁₈₀ (x, y) → (-x, -y)
