Graphing Points Using the Coordinate System

Front

What is the coordinate plane?

Back

A two-dimensional surface where points are defined by a pair of numbers (x, y).

Front

What does an ordered pair represent?

Back

An ordered pair (x, y) represents a specific point on the coordinate plane, where 'x' is the horizontal position and 'y' is the vertical position.

Front

How do you identify the x-coordinate in an ordered pair?

Back

The x-coordinate is the first number in the ordered pair (x, y).

Front

How do you identify the y-coordinate in an ordered pair?

Back

The y-coordinate is the second number in the ordered pair (x, y).

Front

What is the x-axis?

Back

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

Front

What is the y-axis?

Back

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

Front

What is the origin in the coordinate plane?

Back

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

Front

How do you plot a point on the coordinate plane?

Back

To plot a point (x, y), start at the origin, move 'x' units along the x-axis, and then 'y' units up or down along the y-axis.

Front

What does it mean for a point to be in Quadrant I?

Back

In Quadrant I, both the x-coordinate and y-coordinate are positive.

Front

What does it mean for a point to be in Quadrant II?

Back

In Quadrant II, the x-coordinate is negative and the y-coordinate is positive.
