Plotting Points Flashcard

Front

What is a coordinate plane?

Back

A coordinate plane is a two-dimensional surface formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis). It is used to plot points using pairs of numbers called coordinates.

Front

What are coordinates?

Back

Coordinates are a pair of numbers that define the position of a point on a coordinate plane. The first number represents the horizontal position (x-coordinate), and the second number represents the vertical position (y-coordinate).

Front

What does the point (5,8) represent?

Back

The point (5,8) represents a location on the coordinate plane where the x-coordinate is 5 and the y-coordinate is 8.

Front

How do you plot a point on a coordinate plane?

Back

To plot a point, start at the origin (0,0). Move horizontally to the x-coordinate and then vertically to the y-coordinate. Mark the point where you end up.

Front

What is the x-axis?

Back

The x-axis is the horizontal line on a coordinate plane where the y-coordinate is zero. It runs left to right.

Front

What is the y-axis?

Back

The y-axis is the vertical line on a coordinate plane where the x-coordinate is zero. It runs up and down.

Front

What is the origin in a coordinate plane?

Back

The origin is the point (0,0) where the x-axis and y-axis intersect. It is the starting point for plotting points.

Front

What does the point (0,7) represent?

Back

The point (0,7) represents a location on the coordinate plane where the x-coordinate is 0 and the y-coordinate is 7.

Front

What is the significance of the first number in a coordinate pair?

Back

The first number in a coordinate pair is the x-coordinate, which indicates the horizontal position of the point on the coordinate plane.

Front

What is the significance of the second number in a coordinate pair?

Back

The second number in a coordinate pair is the y-coordinate, which indicates the vertical position of the point on the coordinate plane.
