Step 1
First, you 'run' to the right. This gives:

      change in x = 4 - 0
                      = 4 units

Note: Remember to always 'run' first.
The change in x is 4

Step 2
Now, you climb up. This gives:

     change in y = 0 - (-6)
                     = 0 + 6
                     = 6 units

Note: The 'change of y' is always a positive number. This means that you can only climb up.
The change in y is 6

Step 3
From Step 1 and Step 2, you get:
  1. change of x = 4 units
  2. change of y = 6 units
Therefore, the answer is C.
