Exercise 63 Page 220

How many steps should you go to the right or left and up or down from the origin?

Practice makes perfect

To graph the point (x,y), we use the x-coordinate to tell us how far we should move to the right or left from the origin. The y-coordinate shows us how far to move up or down. We have the point (-2,1), so to graph this point we should go 2 steps to the left and 1 step up from the origin.
