Which statement accurately describes how to reflect point A ( -2, 1 ) over the X axis?

A) Construct a line from A perpendicular to the x-axis, determine the distance from A to the x-axis along this perpendicular line, find a new point on the other side of the X-axis that is
equidistant from the x-axis.

B) Construct a line from A parallel to the x-axis, determine the distance from A to the x-axis along this parallel line, find a new point on the other side of the x-axis that is equidistant from the x-axis.

C) Construct a line from A perpendicular to the y-axis, determine the distance from A to the y-axis along this perpendicular line, find a new point on the other side of the y-axis that is equidistant from the y-axis.

D) Construct a line from A parallel to the y-axis, determine the distance from A to the y-axis along this parallel line, find a new point on the other side of the y-axis that is equidistant from the y-axis.

Answer:

A

Step-by-step explanation:

we want to reflect (= mirror) the point over the x axis.

that means the point has to go across the x axis (go to the other side of the x axis).

so, B cannot be right, because a line parallel to the x axis will never hit the x axis, and the point will never get to the other side.

it cannot be C, as this moves the point to the other side of the y axis. but we wanted it on the other side of the x axis.

it cannot be D, as this deals with the distance to the y axis and tries then to move the point again to the other side of the y axis. besides the fact that similar to B that would never work for the y axis, it never deals with transferring the point over to the other side of the x axis.
