Here's your shmoop du jour,

00:04

Rectangle ABCD has vertices as follows.

00:07

If we translate this rectangle 4 units right

00:11

and 2 units down, where is point A's image?

00:14

And here are the possible answers...

00:19

OK. The point is, we're just going to pick up the rectangle where it is right now, and relocate

00:20

The point is, we're just going to pick up the rectangle where it is right now, and relocate

The point is, we’re just going to pick up the rectangle where it is right now, and relocate

00:24

it at a new position. And the new position is 4 units right and

00:28

2 units down. Well, moving to the left and right is shifting

00:32

the x. And up and down is changing the y value. The original position of A is (-4, 6). Going

00:40

to the right is increasing the x value, so

00:43

4 plus negative 4 is 0, so the new x coordinate of point A is 0. That means we can eliminate

00:50

options B, D, and E. Moving down decreases the y value, so we subtract

00:55

2 from the original y. 6 -- 2 is 4, so the new y coordinate is 4.

01:00

The new location of point A is (0, 4)- option A.
