Coordinate Plane Summative

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 x-coordinate represent?

Back

The x-coordinate represents the horizontal position of a point on the coordinate plane, indicating how far to move left or right from the origin (0,0).

Front

What does the y-coordinate represent?

Back

The y-coordinate represents the vertical position of a point on the coordinate plane, indicating how far to move up or down from the origin (0,0).

Front

What is an ordered pair?

Back

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

Front

How do you identify the location of a point (3, -2) on the coordinate plane?

Back

To locate the point (3, -2), start at the origin (0,0), move 3 units to the right along the x-axis, and then move 2 units down along the y-axis.

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 plot the point (-4, 2) on the coordinate plane?

Back

To plot the point (-4, 2), start at the origin (0,0), move 4 units to the left along the x-axis, and then move 2 units up along the y-axis.

Front

What is the distance between the points (2, 3) and (2, -1)?

Back

The distance between the points (2, 3) and (2, -1) is 4 units, calculated as the difference in their y-coordinates: 3 - (-1) = 4.

Front

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

Front

What is a rectangle in the context of the coordinate plane?

Back

A rectangle is a four-sided polygon (quadrilateral) with opposite sides that are equal in length and four right angles, defined by the coordinates of its corners.
