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

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

6. EXAMPLE 1: Determine the quadrant and coordinates for
points A, B, C, D, E, F, G, H, and I on the graph.

7. 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

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

9. 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.
vertical
horizontal X Y X Y
Horizontal table
Vertical table
