How many steps to the right of the origin is the point located? How many steps above it?
Coordinates: (2,2) Quadrant: I
Practice makes perfect
To find the x-coordinate of R, we count the number of units that the point is placed to the right of the origin. Similarly, to find the y-coordinate, we count the number of units that the point is located above the origin.
From the diagram, we see that R is located 2 units to the right of the origin and 2 units above it. Then, its coordinates are x= 2 and y= 2, which we can write as ( 2, 2). To determine the quadrant in which a point lies without graphing, observe the signs of the x- and y-coordinates.

Since both the x- and y-coordinate are positive, the point R(2,2) lies in Quadrant I.
