You start at (5, 3). You move down 3 units and left 6 units. Where do you end?
raketka [301]

Answer:

(-1, 0)

Step-by-step explanation:

5 is the x value which is left and right, so you said u move left 6 units. Since the 5 is positive and left is negative; 5-6= -1. 3 is the y value which is up and down (vertical), so you said u move down 3 units, since the 3 is positive, when you move down that is negative; so 3-3=0.
