Math 1

2. 11.3 Coordinate Plane Vocabulary A
Coordinate Plane: formed by 2 number lines that intersect at right angles in a flat plane. Intersection point is zero (origin) on each line.
Axes: both of the number lines are called axes.
X-axis: horizontal (left-right) line
Y-axis: vertical (up-down) line

3. 11.3 Coordinate Plane Vocabulary B
Quadrants: the two axes divide the coordinate plane into four corners called quadrants.
Ordered Pair: 2 numbers that give the location of a point on a coordinate plane. First number (x) tells how far to move right (positive) or left (negative). The second number (y) tells how far to move up (positive) or down (negative).
Coordinates: the numbers in an ordered pair, called x-coordinate and y-coordinate: (x,y)

4. 11.3 Coordinate Plane Example 1
Give the coordinates of each point A through F
A = (3,-2)
B = (-3,5)
C = (-1,-4)
D = (0,-3)
E = (2,4)
F = (4,0)

5. 11.3 Coordinate Plane Example 2a
Graph each of these points on a coordinate plane: A = (2,3), B = (5,-3), and C = (-1,-5).
First make a graph that will fit all these points.
Next, find each location.
Then put a dot at each.
Last label them A, B, or C.
