These are the problems:

1) Find the image of:

a) x - y = 8 under My=-x followed by translation ( 4, -1 )

b) x + 2y = 8 under R_{-9}followed by translation ( 2, -5 )

c) x + y = 1 under R_{9}followed by My=x followed by translation ( 3, 1 )

The answers are as follows:

a) x - y = 13

b) 2x - y = 5

c) y = x - 3

I have not managed to get the right answers. In your solutions, could you please provide each step of working. Thanks.
