Question

Answer 1

@jim_thompson5910 help

Answer 2

The terminology is that the preimage is the original point and the image is the resulting point (after you translate)

Answer 3

So

preimage ----> image
(x,y) ---> (x+3, y-3)

Answer 4

this means that you need to solve

(x+3, y-3) = (1,1)

or

x+3 = 1
y-3 = 1

for x and y

Answer 5

so then x=2 and y=4

Answer 6

is that right @jim_thompson5910

Answer 7

no

Answer 8

x+3 = 1

x = 1-3

x = -2

Answer 9

y-3 = 1

y = 1+3

y = 4

Answer 10

So you got y correct at least, so that's good
