Exercise 6 Page 177

The x-coordinate represents the horizontal shift, starting from the origin, and the y-coordinate represents the vertical shift.

Practice makes perfect
An ( x, y) ordered pair is plotted in a coordinate plane by finding the x-coordinate on the horizontal axis and the y-coordinate on the vertical axis. For the given point, ( 0, 1), this means tracing 0 units in the horizontal direction starting from the origin, then 1 unit in the positive vertical direction.
