So, for point S with x=3 and y=5 , it will be written as S(3,5) and will be 3 units to the right and 5 units up.

For point T with x=(-2) and y=1, it will be written as T(-2,1) and will be 2 units to the left (pay attention to the negative sign) and 1 unit up.

Point U(-4,-4) is 4 units left and 4 units down (two negative signs this time).

V(2,-5) is 2 units right and 5 units down.

Try for yourself... where would you draw points (1,1) and (-5,7)? What about the two points on the graph that don't have any labels... can you figure out what they should be? Let's call the point on the right W, and the point on the left N. Easy, right? They are W(8,1) and N(-8,7)! All you have to do is count in the proper direction, and you know where your point goes and what its coordinates are! Once you are familiar with how points are labeled and how their positions are calculated, you will be able to work with these numbers to do all sorts of things!

I would love to link to your blog. Mine will eventually get to the topics that you are covering.
