Concepts
How many numbers are needed to plot a point?
Two
What is the center of a graph called?
Origin
Where would the (0,0) be located?
Where the x and y axis cross on a graph?
How is (1,-3) plotted?
right one unit, down three units
What is the difference between the dimensions of a number line and a coordinate plane?
a number line is one dimensional, shows where a number is located in relationship to other numbers.
a coordinate plane is two dimensional, uses coordinates to identify a location
What is an ordered pair?
Two numbers inside parenthesis
What is the name of the vertical line on a graph?
y axis
Where would (x,-y) be located?
Fourth quadrant
How is (-5, 4) plotted?
Down five units, right four
If (2,1) is moved right 3 and up 2, what quadrant would the new point be in?
Quadrant II
What does an ordered pair consist of (be specific!)?
An x and y coordinate that correlates to a specific point on a graph
What is the name of the horizontal axis?
x axis
Where would (-x,-y) be located?
Third quadrant
What is the error in going left 1 and down 6 for (-1,6)?
Go up 6
If (-8,-1) is moved up 4 and left 2, what quadrant is it in?
Quadrant III
What are the coordinates for the origin?
(0,0)
What is a quadrant?
It is a quarter section of the coordinate plane?
If a point lies in Quadrant I, what is true about the coordinates?
Both x and y are positive
What is the error of go right 4 and up 2 for (-4,-2)
Go left 4 and down 2
If (-2,0) is moved right 6 and down 5, what quadrant would the new point be in?
Quadrant IV
What coordinate comes first in an ordered pair, ALWAYS?
x, (hint: x ALWAYS comes first when you sing the ABC song, x ALWAYS comes first in the dictionary, etc.)
What is a coordinate plane?
A graph divided into four parts?
If a point lies in Quadrant II, what is true about the coordinates?
x will be negative and y will be positive
Name a situation in which a point isn't located in a quadrant?
When either coordinate is zero or when the point is at the origin
If (0,0) is moved up 4 and right 9, then down 7 and left 12, what quadrant is the new point in?
Quadrant II
