Graphing Coordinates

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 (x, y).

Front

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

Back

The ordered pair (x, y) represents the position of a point on the coordinate plane, where 'x' is the horizontal distance from the origin and 'y' is the vertical distance from the origin.

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 ordered pair (0, 0).

Front

How do you identify the coordinates of a point?

Back

To identify the coordinates of a point, find its horizontal distance from the y-axis (x-coordinate) and its vertical distance from the x-axis (y-coordinate).

Front

What is the x-axis?

Back

The x-axis is the horizontal line on a coordinate plane where the y-coordinate is zero.

Front

What is the y-axis?

Back

The y-axis is the vertical line on a coordinate plane where the x-coordinate is zero.

Front

How do you plot a point on the 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 is the distance between two points on a coordinate plane?

Back

The distance between two points can be calculated using the distance formula: d = √((x2 - x1)² + (y2 - y1)²).

Front

What is the area of a rectangle on a coordinate plane?

Back

The area of a rectangle can be found by multiplying its length and width, which can be determined from the coordinates of its corners.

Front

What does it mean for points to be 'collinear'?

Back

Points are collinear if they lie on the same straight line.
