if you move (7,2) four units right and units down, what are the coordinates?

Question

I don't understand how to shift a geometric shape on a coordinate plane and then find the coordinate 

Answer 1

A shift to the right or left changes the x coordinate by that amount.  Add if to the right, subtract if to the left.  A shift up or down changes the y-coordinate.  Add for up, subtract for down.  Starting from the point (7,2), a shift of 4 units to the right adds 4 to the 7.  The shift of 2 units down, subtracts 2 from the 2.  The new point will be located at:

 

(7+4, 2-2) = (11,0)
