Question

Triangle ABC is shown below: Triangle ABC is shown. A is at 2, 1. B is at negative 1, 4. C is at 3, 7. If triangle ABC is reflected over the x-axis, which of the following shows the coordinates for point C'?

(−3, 7)

(3, 7)

(−3, −7)

(3, −7)

Answer 1

Your answer would be (3,-7)

Explanation:

If you reflect over the x axis and both of your original coordinates are positive your new coordinates would be (x,-y)

Answer 2

Reflecting across the Y axis would make all the points on the triangle the same distance from the Y axis, just on the opposite side.

Point B is at X = -1, so when reflected across the Y axis would be at X = 1

The Y value would remain the same.

The new location for B would be (1,4)
