Plotting points

Front

What is a point in a coordinate system?

Back

A point is a specific location in a two-dimensional space, represented by an ordered pair of numbers (x, y).

Front

What does the first number in an ordered pair represent?

Back

The first number represents the horizontal position (x-coordinate) on the coordinate plane.

Front

What does the second number in an ordered pair represent?

Back

The second number represents the vertical position (y-coordinate) on the coordinate plane.

Front

What is the origin in a coordinate system?

Back

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

Front

How do you plot a point (3, 2) on a graph?

Back

Start at the origin (0, 0), move 3 units to the right (x-axis), and then 2 units up (y-axis).

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to locate a point on a coordinate plane, written as (x, y).

Front

What is the x-axis?

Back

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

Front

What is the y-axis?

Back

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

Front

What does it mean for a point to be in the first quadrant?

Back

A point is in the first quadrant if both its x and y coordinates are positive.

Front

What does it mean for a point to be in the second quadrant?

Back

A point is in the second quadrant if its x coordinate is negative and its y coordinate is positive.
