Coordinate grid

Front

What is a coordinate grid?

Back

A coordinate grid is a two-dimensional plane formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis), used to locate points using ordered pairs.

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to locate a point on a coordinate grid, written in the form (x, y), where x is the x-coordinate and y is the y-coordinate.

Front

What is the x-coordinate in an ordered pair?

Back

The x-coordinate is the first number in an ordered pair (x, y) that indicates the horizontal position of a point on the coordinate grid.

Front

What is the y-coordinate in an ordered pair?

Back

The y-coordinate is the second number in an ordered pair (x, y) that indicates the vertical position of a point on the coordinate grid.

Front

How do you identify a point on a coordinate grid?

Back

To identify a point, locate the x-coordinate on the x-axis, then move vertically to find the corresponding y-coordinate.

Front

What does the point (0, 0) represent on a coordinate grid?

Back

The point (0, 0) is called the origin, where the x-axis and y-axis intersect.

Front

How do you write an ordered pair for the point located 3 units right and 2 units up from the origin?

Back

The ordered pair would be (3, 2).

Front

What is the distance formula for finding the distance between two points (x1, y1) and (x2, y2)?

Back

The distance formula is d = √((x2 - x1)² + (y2 - y1)²).

Front

If a point is located at (5, 7), what is its x-coordinate?

Back

The x-coordinate is 5.

Front

If a point is located at (4, 9), what is its y-coordinate?

Back

The y-coordinate is 9.
