Answer:

4

Step-by-step explanation:

y=3 is a horizontal line, so it will not affect the x coordinate.

The x-coordinate of  the image when M(4,-1) is reflected in y = 3 is : 4

What is reflection?

Reflection is the mirror image of a shape.

It is the process of flipping a shape around a certain axis to look like the original shape.

Analysis:

Since the reflection is at y = 3 which is along the x-axis, only the y coordinate changes.  The x coordinate remains the same. So, the x- coordinate is still 4.

In conclusion, the x-coordinate is 4.
