Explanation:

Check out the diagram below for a visual.

The line x = 2 is a vertical line in which every point on this line has x coordinate 2. Two points on this line are (2,0) and (2,1).

The point (-2,4) is 4 units away in the horizontal direction from the line x = 2. Basically we start at (-2,4) and move 4 units to the right to arrive at (2,4). Move 4 more units to arrive at (6,4).

In short: we reflect (-2,4) over the line x = 2 and it lands on (6,4)

We see that choice C must be the answer as no other answer choices have (6,4). So if you are pressed for time, you can stop here.

Let's keep going for the sake of completeness

We'll follow the same steps for the point (-1,5).

Move 3  units to the right to go from (-1,5) to (2,5). The goal again is to reach the vertical line x = 2

Then move another 3 units to the right to arrive at (5,5)

(-1,5) reflects over x = 2 to land on (5,5).

the answer is a if my teacher taught me correct
