Point G translated right 0, up 5 A. (–4, 1) B. (–4, 9) C. (–4, 4) D. (1, 4) http://static.k12.com/calms_media/media/1419500_1420000/1419560/1/6e8d179d12e56ca8b6089fc1dff30e32472eed83/FGA_130921_1614041.jpg

OpenStudy (mathstudent55):

Can you read the coordinates of point G as it is now before the translation?

OpenStudy (jojo12g):

no

OpenStudy (mathstudent55):

OK. This is how you read a point of the x-y coordinate plane.

OpenStudy (jojo12g):

4 , -4

OpenStudy (mathstudent55):

An ordered pair is written in a specific order. We usually write the x-coordinate first, followed by the y-coordinate. x is left and right, the horizontal axis. y is up and down, the vertical axis.

OpenStudy (jojo12g):

-4 ,4

OpenStudy (mathstudent55):

Here is the x-y coordinate plane. |dw:1433179326608:dw|

OpenStudy (jojo12g):

k

OpenStudy (mathstudent55):

The reason an ordered pair is called an ordered pair is that the order makes a difference. You must always read the x value before the y value. Remember, x is left and right. y is up and down.

OpenStudy (jojo12g):

k

OpenStudy (jojo12g):

so the answer is c
