Plotting Points

Front

What is a coordinate point?

Back

A coordinate point is a pair of numbers that define a specific location on a Cartesian plane, represented as (x, y).

Front

What does the first number in a coordinate pair represent?

Back

The first number (x) represents the horizontal position on the Cartesian plane, indicating how far to move left or right from the origin.

Front

What does the second number in a coordinate pair represent?

Back

The second number (y) represents the vertical position on the Cartesian plane, indicating how far to move up or down from the origin.

Front

How do you plot the point (-1, 1)?

Back

Start at the origin (0, 0), move left 1 unit (to -1 on the x-axis), then move up 1 unit (to 1 on the y-axis).

Front

What is the ordered pair for point H?

Back

(1, 2)

Front

How do you plot the point (-2, -6)?

Back

Start at the origin (0, 0), move left 2 units (to -2 on the x-axis), then move down 6 units (to -6 on the y-axis).

Front

What is the significance of the origin in a Cartesian plane?

Back

The origin is the point (0, 0) where the x-axis and y-axis intersect, serving as the reference point for all other points.

Front

What is the ordered pair for point K?

Back

(3, -3)

Front

What point is located at (3, -2)?

Back

Point D.

Front

What does it mean to move 'left' on a Cartesian plane?

Back

Moving left means decreasing the x-coordinate value.
