Answer 2

a) first: (x,y)--->(-x,y) then (x1,y1)--->(x+2,y-2) Does that make sense?

Answer 3

So I put that down for a?

Answer 4

That's what you would use to solve for the vertices of the triangle.

Answer 5

Ok.. So what would you put down for a?

Answer 6

I will help you solve for A then if you need more help you can ask me.

A-(1,3)
(1,3)--->(-1,3) (-1,3)--->(0,1)
New point for A after the reflection and translation-(0,1)

Answer 7

Can you hold on I have to help my mom

Answer 8

Yeah that's fine

Answer 9

So just type that into the answer?

Answer 10

For one of the points yes, but you have to try solving for the new points of B and C
