The point (2.1.-3.5) is reflected over the x-axis, what is the coordinate of that point of reflection?

2nd answer, (2.1,3.5)

Step-by-step explanation:

Reflection over x axis rule:

(x,-y) Change the sign of the y coordinate.

So we basically change the sign of the y axis (-3.5) to get (3.5).

Very much simple and I hope it helps.
