Standard: 5.G.A.1
Use a pair of perpendicular number lines, called axes, to define a coordinate system, with the intersection of
the lines (the origin) arranged to coincide with the 0 on each line and a given point in the plane located by
using an ordered pair of numbers, called its coordinates. Understand that the first number indicates how far to
travel from the origin in the direction of one axis, and the second number indicates how far to travel in the
direction of the second axis, with the convention that the names of the two axes and the coordinates
correspond (e.g., x-axis and x-coordinate, y-axis and y-coordinate).

Task Exemplars:
1. Circle “True” or “False” for each of the statements below:
The x- and y-axes are parallel lines.
True
False
The x- and y-axes are perpendicular lines.
True
False
The x- and y-axes intersect at the origin.
True
False
The x- and y-axes intersect at 5.
True
False
The x- and y-coordinates are used to locate
points on a coordinate plane.
True
False
2. Look at the table below. Plot and label points C and D on the coordinate plane.
Then write ordered pairs for the points and describe how to move from (0, 0) to
get to each point.

3. Part A:
Select the three statements below that correctly describe the plotted point on the
coordinate grid.
M
A. The x-coordinate is 2 and the y-coordinate is 4.
B. The y-coordinate is 4 and the x-coordinate is 2.
C. The point is located at the ordered pair (2, 4).
D. The point is located at the ordered pair (4, 2).
E. The point is 4 units to the right of the origin on the x-axis and 2 units
up from the origin on the y-axis.
F. The point is 2 units to the right of the origin on the x-axis and 4 units
up from the origin on the y-axis.
Part B:
Deanna identified the ordered pair for point M on the coordinate plane as (2, 4). Is
Deanna correct? Why or why not?
