Circle the correct answers
20 pixels to the left means x is (increasing / decreasing) by 20
50 pixels up means y is (increasing / decreasing) by 50
dx = (change in x / change in y)
dy = (change in y / change in cow)

Since this zone is usually used for homework, I'll let you figure it out from here.
