Exercise 2 Page 173

Start at the origin. Move horizontally to find the x-coordinate and then vertically to find the y-coordinate of the point.

(2,0)

Practice makes perfect
To identify the (x,y) ordered pair to which a given point corresponds, start at the origin and move horizontally to find the x-coordinate, then move vertically to find the y-coordinate of the point. In this case, point D lies on the x-axis and is 2 units to the right of the origin. So, the x-coordinate is 2 and the y-coordinate is 0.

Therefore, point D lies at the coordinate pair (2,0).
