Whoever answers this right in 3 mins gets the coordinates of a quadrilateral are

D) reflection across the x-axis

Step-by-step explanation:

Given : The coordinates of a quadrilateral are (1, 2), (4, 2), (1, 4), and (4, 4). After a transformation, the new coordinates are (1, −2), (4, −2), (1, −4), and (4, −4).

Here, the sign of the y-coordinates are changed in the image . [Rest other things remained same.]

Since , it happens in reflection across the x-axis by using rule :

It means the quadrilateral reflected across the x-axis.

Hence, the transformation occurred : reflection across the x-axis

Step-by-step explanation:

Its the last one: a translation 2 units right and 4 units down.

Step-by-step explanation:

To get from point E (1,3) to E' (3-1) you add 2 units to the x coordinate since the x-axis goes from left to right  and moving to the right means its positive and then you subtract 4 from the y coordinate since the y axis is going up and down and when you move -4 points you move down 4 points. You do this to every other point get the new figure.
