Question

Someone please help me on this plz

Answer 1

Answer:

17) (2,-1)

18) (3,-7)

1,3, and 4 are isometric because they preserve the size of the shape. 2 is not an isometry because the size of the shape changes.

Step-by-step explanation:

To find the translation in the first 2 questions, you would first choose a reference point on the original shape (like point S). Then, you count the number of units it moved in the x-direction (to the right 2) which is the x coordinate. Then, you count the number of spaces it moved in the y-direction (down 1) which corresponds to the y coordinate -1.

Answer 2

Answer:

Everything you need is down below

Step-by-step explanation:

17.) (x + 2, y - 1)

18.) (x + 3, y - 7)

PAGE 2

1.) Yes, b/c isometry is when two points have the same distance and this image looks like it was flipped upside down.

2.) No, this is a dilation not an isometry

3.) Yes, b/c they are the same size and the shape could have been flipped upside down, to the left, right, or up.

4.)  Yes, b/c the shape has been flipped to the right and it has the same size.

9.) Plug in (2 - 8, 6 + 4)

A'(-6, 10)

10.) (-1 - 8, 5 + 4)

B'(-9, 9)

11.) Reverse it (-3 + 8, -10 - 4)

C(5, -14)

12.) Reverse it (4 + 8, -3 - 4)

D(12, -7)
