Answer:
From A to B the change in Y is 6,
From A to B the change in X is 2.
Explanation:
To find the change in Y you subtract 0 in (3,0) from 6 in (1,6) because the Y is always the SECOND number in a set of parenthesis. To find the change in X you subtract the 1 in (1,6) from the 3 in (3,0) because the x is always the FIRST number in a set of parenthesis.
