Plz help! will give brainliest! Triangle FIT has been reflected over the y-axis. Which of the following best describes the relationship between the y-axis and the line connecting F to F′? They share the same midpoints.
They are diameters of concentric circles.
They are perpendicular to each other.
They are parallel and congruent.

Step-by-step explanation:

If the original coordinates of K were

The new coordinates will be

In fact, a reflection over the y-axis changes the sign of the x coordinate, and leaves the y coordinate unchanged.

So, the line connecting K and K' has slope

and thus it is horizontal.

Any horizontal line is perpendiculat to the y axis.

They are perpendicular to each other.

Step-by-step explanation:

Reflection over y-axis,  as a result point F(x, y) changes to F'(-x, y)

Since y- coordinate stays as is the line is horizontal, and it is perpendicular to y-axis

So the third answer choice is correctly reflecting this condition

why can't you?
