a. Write the rule for this translation.
b.What are the coordinates of the image point?

A.(x,y)=(x+4,y+1); (7, -2)
B(x,y)=(x-4,y-1); (-1, 0)
C.(x,y)=(x+4,y+1); (-1, 0)
D.(x,y)=(x-4,y+1); (-1, 0)

well,
right and up are in a positive direction (add to x,y)
left and down are in a negative direction (subtract from to x,y)

NOW what would you say?
Just draw a graph. See how it works. By the way, can you tag on a picture on this response?
