Triangle ABC is reflected over the x-axis. Triangle ABC has points A (10, 2), B (9, 5), and C (6, 4). What is the B' coordinate?

Answer 1

B has a point of (9,5); now you need a different scale for B´; maybe 1:2?‡

Answer 2

Reflecting over the X-axis means the x-coordinate will remain the same........ +9 and the y-coordinate will go from positive to negative............ -5.

Answer: B' is (9, -5)

Answer 3

When you reflect over the x axis, the y coordinate changes signs. Your point B is (9,5) The y coordinate is 5. Since it is positive, it would become negative. The new point B' is (9,-5)
