Can someone me with the last question because i didnt express the coordinates algebraically because i didn't know how

I think that it should be (x+4, y-1) because you are starting with (x,y) and each one is translated by a number because it moved across(x) 4 and down(y) 1

You would move the (5,0) to the right 4 witch would make the 5 a 9 than you would move the 0 down one which would make it a -1 so that new one would be (9,-1) the next one you chose would be would be (8,0) for the same reason of moving it to the right 4 which would make that 4 an 8 and than moving the 1 down that would make it 0.
