A triangle has vertices at F (-7, 3), G (2, 6), and H (3, 5). What are the coordinates of each vertex if the triangle is reflected over the x-axis?

A) F ¢(7, - 3), G ¢(-2, - 6), H ¢(-3, - 5)
B) F ¢(-7, 3), G ¢(-2, 6), H ¢(-3, - 5)
C) F ¢(-7, - 3), G ¢(2, - 6), H ¢(3, - 5)
D) F ¢(7, 3), G ¢(-2, 6), H ¢(-3, 5)

Final answer:

To find the reflected coordinates of a triangle over the x-axis, negate the y-coordinates of each vertex. The correct reflected coordinates are F'(-7, -3), G'(2, -6), and H'(3, -5).

Step-by-step explanation:

The question asks for the coordinates of the vertices of a triangle once it is reflected over the x-axis. When a point is reflected over the x-axis, its x-coordinate remains the same, but the sign of its y-coordinate is changed. So, to find the coordinates of the vertices of the reflected triangle, we only need to negate the y-coordinates of each original point. Applying this to the given vertices

  • For F (-7, 3), the reflected point is F'( -7, -3)
  • For G (2, 6), the reflected point is G'(2, -6)
  • For H (3, 5), the reflected point is H'(3, -5).

Thus, the correct set of reflected coordinates is option C: F'(-7, -3), G'(2, -6), H'(3, -5).
