Graphing Coordinates

Front

What is a coordinate plane?

Back

A coordinate plane is a two-dimensional surface where points are defined by a pair of numbers (coordinates) representing their position.

Front

What do the two numbers in a coordinate pair represent?

Back

The first number represents the horizontal position (x-coordinate) and the second number represents the vertical position (y-coordinate).

Front

Why are coordinate planes used?

Back

They are used to show locations of points in a two-dimensional space.

Front

What is the origin in a coordinate plane?

Back

The origin is the point where the x-axis and y-axis intersect, represented by the coordinates (0,0).

Front

How do you read coordinates?

Back

Coordinates are read as (x, y), where x is the horizontal value and y is the vertical value.

Front

What are the coordinates of the point located 3 units right and 2 units up from the origin?

Back

(3, 2)

Front

What are negative coordinates?

Back

Negative coordinates are values that are less than zero, indicating a position to the left of the origin on the x-axis or below the origin on the y-axis.

Front

What are the coordinates of the point located 1 unit left and 4 units down from the origin?

Back

(-1, -4)

Front

How do you plot a point on a coordinate plane?

Back

To plot a point, start at the origin, move horizontally to the x-coordinate, and then vertically to the y-coordinate.

Front

What is the x-axis?

Back

The x-axis is the horizontal line on a coordinate plane where y=0.
