Answer 1

That's a lot of question. What specific concept do you need help on?

Answer 2

Translations?

Answer 3

Everything!! I don't know how to do anything!! @mhchen

Answer 4

Do you at least know what a

Reflection
Translation
Dilation

is?

Answer 5

Okay so a Reflection basically flipping something, like what you see in a mirror.

Answer 6

A Translation is moving it up, down, left, right.

Answer 7

And a Dilation is making it bigger or smaller.

Answer 8

So let's look at problem 6:

Mapping STUV to WXYZ

You should know that
S-->W
T-->X
U-->Y
V-->Z

Answer 9

So if you look at the graph, you'll notice that the rectangle has to FLIP to the right, across the Y-Axis. Pretend the Y-axis is like a mirror, and you just reflected its image across of it.

Answer 10

What answer choices does it give you to select from for the notations?

Answer 11

(x,-y)
(-x,y)
(-x,-y)

Answer 12

Alright, so according to the graph on Problem 6.

Answer 13

You are moving from the (-x, y) place to (x, y)

Basically the x-value gets MULTIPLIED BY -1

(-x , y) --> (x, y)
