Plot point A at (4,3). Translate point A left 5 units. Label this point B. Give the coordinates of point B.

Not going to plot the points for you. I expect that is within your comprehension.

If you plot point B five units to the left of A, that means x is going to decrease by 5. That means that the coordinates of B are B(4 - 5, 3) = B(-1, 3).

Hope this helps.

b.-4 units

all you   do is count how many times you move
