Question

1.Which choice describes the translation represented by the translation rule (x,y)--->(x+4,y-1)?
4 units to the right and 1 unit down
1 unit to the right and 4 units down
4 units to the left and 1 unit up
4 units to the left and 1 unit down

2.Use a translation rule to describe the translation that is 10 units to the left and 3 units down.

(x, y) → (x + 10, y + 3)
(x, y) → (x – 10, y + 3)
(x, y) → (x – 10, y – 3)
(x, y) → (x + 10, y –3)

Answer 1

translation rule:
if you add to X then it goes the right
if you subtract from X then it goes to the right

if you add to Y then it goes UP
if you sub from Y then it goes DOWN

Answer 2

see if you can apply that and answer the questions

Answer 3

Even if you subtract X it goes to the right?

Answer 4

So 1 is A?

Answer 5

oops - that should be "subtract" goes to the right...
yes 1 is A
