Graphing With Coordinates

• Section 1.4

2

• A plane that is divided into 4 regions by a
• vertical and horizontal number line is called
• a _______________________.

coordinate plane
3
The four regions of a coordinate plane are
called _________________.
The point at which the x-axis and y-axis
intersect is called the _______________.
The horizontal line is called the _____________.
x-axis
The vertical line is called the ________________.
y-axis
quadrants
origin

• The order in which you name a point is
• important which is why the coordinates of
• the point are called an ______________.

ordered pair

EXAMPLE 1

• Determine the quadrant and coordinates for
• points A, B, C, D, E, F, G, H, and I on the graph.

A (4, 2) QI
B (0, 2) y-axis
C (-4, 1) QII
D (-3, 0) x-axis
E (-3, -3) QIII
F (2, -3) QIV
G (0, -4) y-axis
H (0, 0) origin
I (2, 0) x-axis

• Example 2 Graph each of the following points on
  the coordinate plane.

R( -1, 2)
T( 0, -3)
H( -5, -4)
M( 5, 3)

• Sometimes when we talk about a set of ordered
• pairs we make a table to show the values of x and
  y.
• The table can be written in ______________ or
  ___________________ form.
