Question

Which rule describes this transformation?

Answer 1

Answer: A. (x,y) → ( x+4,y-5)

Explanation:

This a rigid transformation and is being translated to find the transformation you could use any vertex.

Using the image of B and to get to B prime we have to move 4 units to the right and 5 units down.

So we could describe the whole transformation as (x,y) → ( x+4,x-5)

Answer 2

`(x+4,y-5)`

Explanation:

Studying the figures ABCD and A'B'C'D', we can look at just one point and figure out the transformation from that.

Point A is at (-7, 8)

Point A' is at (-3, 3)

If we look at the x values, -7 and -3, we can see that the value changed by 4. So
`x+4` will be what the x becomes.

Also looking at the y values, we can see that the values were 8 and 3 - that's a change of -5, so our y is
`y-5`.

Combining these, we get
`(x+4, y-5)`.

Hope this helped!
