    a translation is when you take something and move it elsewhere so efectivly a reflection is also a translation.

    the answer is B. B. vertical translation of 10 units. It cannot be a reflection, note that H has a vertex at (4,2) and the reflection about X-axis will have vertex at (4,-2) but the figure H prime (the bottom one) has a vertex at (4,-3). Thus on reflection the figures won't overlap. Only way to do that is to slide down the figure above 10 units to the bottom.

    it cannot be a reflectio cuz, in mirror if u see, preimage is at same distance from the image. but here thats not the case..

    it does look like a reflection cuz it has horizontal symmetry.. if it was translated just 9 units down, then its both translation and reflection
