Plotting points

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 in the form (x, y).

Front

What does the first number in an ordered pair represent?

Back

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

Front

What does the second number in an ordered pair represent?

Back

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

Front

How do you plot the point (5, 3) on a coordinate plane?

Back

Start at the origin (0, 0), move 5 units to the right (x-axis), and then move 3 units up (y-axis).

Front

What is the coordinate of the origin on a coordinate plane?

Back

The origin is at the point (0, 0).

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 is the significance of negative coordinates?

Back

Negative coordinates indicate positions to the left of the y-axis (for x) or below the x-axis (for y).

Front

How do you identify the point at (0, 4)?

Back

The point (0, 4) is located on the y-axis, 4 units above the origin.

Front

What is the point at (-1, 3)?

Back

The point (-1, 3) is located 1 unit to the left of the y-axis and 3 units above the x-axis.
