Coordinate Plane Graphing

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).

Front

What are the x-axis and y-axis?

Back

The x-axis is the horizontal line on a coordinate plane, while the y-axis is the vertical line.

Front

How do you plot a point on a coordinate plane?

Back

To plot a point, start at the origin (0,0), move along the x-axis to the x-coordinate, and then move vertically to the y-coordinate.

Front

What does the coordinate (0,0) represent?

Back

The coordinate (0,0) represents the origin, where the x-axis and y-axis intersect.

Front

What is the first number in a coordinate pair called?

Back

The first number is called the x-coordinate.

Front

What is the second number in a coordinate pair called?

Back

The second number is called the y-coordinate.

Front

What does it mean if a point has a negative x-coordinate?

Back

A negative x-coordinate means the point is located to the left of the origin.

Front

What does it mean if a point has a negative y-coordinate?

Back

A negative y-coordinate means the point is located below the origin.

Front

How do you identify the quadrant of a point?

Back

The quadrant can be identified based on the signs of the x and y coordinates: Quadrant I (+,+), Quadrant II (-,+), Quadrant III (-,-), Quadrant IV (+,-).

Front

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

Back

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