It is a translation of the shape on the coordinated grid
It could be a reflection with the mirror line outside the figure; it could be a rotation with the centre of rotation outside the figure; or it could be a translation.
It is called a rotation.
I never learned a rule for reflection, but the easiest method would be to count the number of points the point of your figure/line from the x- axis or y-axis, and apply the same number onto the other side. That's how I always did it. It you were to just move the whole figure over, that would only be translation! make sure the figure/line makes sense of where it is.
A translation of a figure is when a figure changes it's position, And can be in the direction of up, down, left, right, and maybe diagonal.

A translation, a reflection and a rotation
This is a transformation which could be a rotation, translation or reflection.

It will be as you term it 'horizontal stretch' in which the figure is enlarged or reduced in size.
Figures are congruent if and only if they are related by a translation, reflection, or rotation, or some combination of these transformations.
A transformation is moving or changing the shape of a figure on the Cartesian plane by a translation, by a reflection, by a rotation or by an enlargment
In mathematical terms, the figure that is made after a transformation is what is known as an image. Prior to the chance, the figure is called the pre-image. Changing into an image can take place after four types of mathematical transformations: translation, reflection, rotation and dilation.
The input of a transformation on the coordinate plane is called the "preimage." The preimage is the original figure before any transformation, such as translation, rotation, reflection, or dilation, is applied to it. After the transformation, the resulting figure is referred to as the "image."
