graphing on coordinate plane

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). Each point on the plane is defined by an ordered pair of numbers (x, y).

Front

What does the ordered pair (0, 3) represent on a coordinate plane?

Back

The ordered pair (0, 3) represents a point located at the origin on the x-axis (0) and 3 units up on the y-axis.

Front

When plotting points, which direction do you move first?

Back

You move left or right along the x-axis first, then up or down along the y-axis.

Front

What is the x-coordinate in the ordered pair (7, -7)?

Back

The x-coordinate is 7.

Front

What is the y-coordinate in the ordered pair (7, -7)?

Back

The y-coordinate is -7.

Front

How do you find the distance from the origin to the point (3, 4)?

Back

Use the distance formula: distance = √(x² + y²). For (3, 4), distance = √(3² + 4²) = √(9 + 16) = √25 = 5.

Front

What does the point (2, 7) indicate on a coordinate plane?

Back

The point (2, 7) indicates a location 2 units to the right of the origin and 7 units up.

Front

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

Back

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

Front

What is the term for the horizontal line in a coordinate plane?

Back

The horizontal line is called the x-axis.

Front

What is the term for the vertical line in a coordinate plane?

Back

The vertical line is called the y-axis.
