*For point 1: We have that a translation is an un-interrupted movement without transforming the shape, so the term that best describes it is "slide".
*For point 2: The translation that is shown is: four units to the left and two units up.
*For point 3: The translation that is shown is: two units right and six units down.
*For point 4: The dilation that is shown is: the shape increases by two times in the x-axis and increases by two times in the y-axis.
