Answer:
(7, 8)
Step-by-step explanation:
If Sidney places each piece 3 units east and 2 units north of the last one, we can figure out which coordinate comes first by subtracting the position of the second piece (S) by the position of the first piece (F):
[tex]S - F = (4,6) - (1,4) = (3,2)[/tex]
We can conclude that coordinates are in the (East, North) format.
Therefore, the location of the third piece (T) is:
[tex]T = S(E,N) +(3,2)= (4,6)+(3,2)\\T = (7,8)[/tex]
