    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:

    • change of x = 4 units
    • change of y = 6 units

    Therefore, the answer is C.
