Okok I understand. I think of it as basically making x/y equal to something in the new equation then subbing it in, sort of like reducible equations.

I have a few that I'm confused about, these ones have more than one step:

to

This is what I've done...

so...

and

**no, it's not ready to classify the image points yet**
So...

and

The answers say: A dilation factor of 2 from the x axis followed by a translation determined by the vector (0,-3) (this should be vertical).

How can it be a dilation factor of 2 from the x axis... that is

How come I get +3 and it says -3?

Also..

to

I don't rearrange the equation because I think it is fine... so..

**no, it still needs work!** and

Is this correct? What do I do from here

Also I just want to say how much I appreciate the help from you guys, I love you guys soo much!!
