Coordinate Plane 1
The sections in a coordinate plane
Quadrants
This is the axis you plot first
x-axis
This axis is horizontal (left and right)?
Which quadrant is the point (4, –2) located in?
Quadrant IV
This is axis is vertical (UP & Down)?
y-axis
The number of quadrants in a coordinate plane
Four
What quadrant has (-,-) values (numbers)?
Quadrant III
What quadrant is (-4, 0) in?
None
What quadrant has (+,-) values (numbers)?
Quadrant IV
The way ordered pairs are written
(x,y)
The name for the point (0,0) on a coordinate plane
The origin
The direction from zero when you are plotting the second number (-3, 7)
Up
Starting at the origin, how many units right/left and how many units up/down do you go to get to point (3, -2)?
Right 3 units, down 2 units
The direction from zero you go first when plotting this ordered pair (-1, 9)
Left
What quadrant contains the ordered pair (-3,1).
Quadrant II
The point (4, 2) is reflected across the y-axis, then moves down 3 units. What is the new coordinates for the point?
(-4, -1)
What quadrant contains the reflection of (-5, -4) across the x-axis?
Quadrant I
The point (-2, 6) is reflected across the x-axis, then moves up 7 units. What quadrant is the new point in?
Quadrant II
Starting at (-5, 8), how many units right/left and how many units up/down do you go to get to point (3, -2)?
Right 8 units, down 10 units
The point (-9.04, 7.77) is reflected across the y-axis, then reflected over the y-axis again. What are the coordinates of the new point?
(-9.04, 7.77)
A battleship is sailing in an ocean that has its locations mapped out on a coordinate plane. Right now, the ship is at point (2, 5). The captain wants to find the fastest route to get the ship to the y-axis. What direction does he have to move and how many units?
Left 2 units.
Point P is located at (–2, –1).
It is reflected over the x-axis, then over the y-axis, then over the x axis again. What is the final ordered pair of Point P?
(2, -1)
Point P is located at (–2.36, 8.99).
It is reflected over the x-axis, then over the y-axis, what is the final ordered pair of Point P?
(2.36, -8.99)
A battleship is sailing in an ocean that has its locations mapped out on a coordinate plane. Right now, the ship is at point (1, -4). What quadrant will the ship be in if it sails down 5 units and right 12 units.
Quadrant IV?
A battleship is sailing in an ocean that has its locations mapped out on a coordinate plane. Right now, the ship is at point (-5, -2). Give the new position of the ship if it sails up 5 units and left 4 units.
What is (-9, 3)?
