Graph points review (positive numbers only)

Review graphing points and identifying points on quadrant I of a coordinate plane.  Then, try some practice problems. 

Graphing points in the coordinate plane

Points in the coordinate plane are identified by coordinates given in the form (x,y).
The x-coordinate represents a value on the horizontal axis.
The y-coordinate represents a value on the vertical axis.
Example:
Plot the point (6,4).
For (6,4) our x-coordinate is 6, and our y-coordinate is 4.
Let's start by going right to 6 on the x-axis:
Now we go up to 4 on the y-axis, and plot the point (6,4):

Identifying points

To determine the coordinates (or ordered pair) of a given point, we need to count the horizontal and vertical distance of the point from the origin (0, 0).
Example:
Use the following coordinate plane to determine the ordered pair for the given point.
Let's start by counting the distance from (0,0) to the given point on the x-axis:
The point is 3 units to the right of the origin.
Now let's count the distance from (0,0) to the given point on the y-axis:
The point is 1 unit above the origin.
The coordinates of the point are (3,1).

Practice set 2: Identifying points

Problem 2A
What is the x-coordinate of the point plotted below?
  • Your answer should be
  • an integer, like 6
  • a simplified proper fraction, like 3/5
  • a simplified improper fraction, like 7/4
  • a mixed number, like 1 3/4
  • an exact decimal, like 0.75
  • a multiple of pi, like 12 pi or 2/3 pi
