Plotting Points
What is a coordinate plane?
A two-dimensional surface formed by the intersection of a vertical line (y-axis) and a horizontal line (x-axis)
Define "quadrant."
One of the four sections of a coordinate plane, divided by the x and y axes.
How do you plot (2, -3)?
Move 2 units right (positive x-direction) and 3 units down (negative y-direction).
What quadrant is the point (1,3) in?
Quadrant I
How many quadrants are on a coordinate plane?
4
What does the x-coordinate represent?
The horizontal position of a point on a coordinate plane.
What is an ordered pair?
A pair of numbers used to locate a point on a coordinate plane, written in the form (x, y).
What is the first quadrant?
The section of the coordinate plane where both x and y coordinates are positive.
What is the point that we start at before plotting a coordinate?
Origin
What quadrants are below the x-axis?
3 and 4
What does the y-coordinate represent?
The vertical position of a point on a coordinate plane.
Explain what a grid is.
A network of horizontal and vertical lines that form squares, used to help locate points.
Describe how to plot the point (-1, 5).
to the left 1 and up 5
Which axis is vertical?
Y-Axis
What quadrant is the coordinate (-3,5) in?
What is Quadrant II
Describe how to Plot the point (3, 4) on a graph.
What does "axes" refer to?
The two perpendicular lines (x-axis and y-axis) that define the coordinate plane.
How can you determine if a point is in Quadrant III?
Both the x and y coordinates are negative.
Explain how to graph (5,-3)?
5 right and 3 down
Which axis is horizontal
X-axis
What are the coordinates of the origin?
Answer: (0, 0).
Describe "negative coordinates."
Coordinates that have negative values, found in Quadrants II and III on the coordinate plane.
How can you determine if a point is in Quadrant IV
The x is positive coordinate and y coordinate is negative.
What are the coordinates if you move 5 units right?
(5,0)
If the point is on the x or y axis, one of the values must be?
Zero
