Plotting points

Front

What is a point in a coordinate system?

Back

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

Front

What does the ordered pair (x, y) represent?

Back

The ordered pair (x, y) represents the horizontal (x) and vertical (y) positions of a point on a coordinate plane.

Front

What is the x-coordinate?

Back

The x-coordinate is the first number in an ordered pair, indicating the horizontal position of a point.

Front

What is the y-coordinate?

Back

The y-coordinate is the second number in an ordered pair, indicating the vertical position of a point.

Front

What does the point (0, 0) represent?

Back

The point (0, 0) is called the origin and is the starting point of the coordinate system.

Front

How do you identify a point on a graph?

Back

To identify a point, locate the x-coordinate on the horizontal axis and the y-coordinate on the vertical axis, then find where they intersect.

Front

What is the significance of negative coordinates?

Back

Negative coordinates indicate positions to the left of the origin on the x-axis or below the origin on the y-axis.

Front

What letter corresponds to the ordered pair (1, 1)?

Back

The letter corresponding to (1, 1) is A.

Front

What letter corresponds to the ordered pair (2, 2)?

Back

The letter corresponding to (2, 2) is B.

Front

What letter corresponds to the ordered pair (3, 3)?

Back

The letter corresponding to (3, 3) is C.
