Coordinate Planes Practical Problems Practice

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 locate points using ordered pairs (x, y).

Front

What are the four quadrants of a coordinate plane?

Back

The four quadrants are: Quadrant I (x > 0, y > 0), Quadrant II (x < 0, y > 0), Quadrant III (x < 0, y < 0), Quadrant IV (x > 0, y < 0).

Front

What is the origin in a coordinate plane?

Back

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

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

How do you identify the x-coordinate of a point?

Back

The x-coordinate is the first number in an ordered pair (x, y) and indicates the horizontal position on the coordinate plane.

Front

How do you identify the y-coordinate of a point?

Back

The y-coordinate is the second number in an ordered pair (x, y) and indicates the vertical position on the coordinate plane.

Front

What does it mean for a point to be on the x-axis?

Back

A point is on the x-axis if its y-coordinate is 0, meaning it lies horizontally along the x-axis.

Front

What does it mean for a point to be on the y-axis?

Back

A point is on the y-axis if its x-coordinate is 0, meaning it lies vertically along the y-axis.

Front

What are the coordinates of a point that is 3 units below (-3, 6)?

Back

The coordinates are (-3, 3).

Front

Which quadrant contains points where both x and y are negative?

Back

Quadrant III contains points where both x and y are negative.
