NC5G1 Plot Points on a Coordinate Grid

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

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

• The ordered pair (x, y) represents the slope of a line on a graph.

• The ordered pair (x, y) represents the area of a rectangle defined by the coordinates.

• The ordered pair (x, y) represents the distance between two points on a number line.

What is the y-axis?

• The horizontal line on a coordinate grid where the y-coordinate is zero.

• The vertical line on a coordinate grid where the x-coordinate is zero.

• The line that represents the slope of a graph.

• The line that divides the graph into quadrants.

What does it mean to move 'north' on a coordinate grid?

• Moving down along the y-axis, which decreases the y-coordinate.

• Moving up along the y-axis, which increases the y-coordinate.

• Moving left along the x-axis, which decreases the x-coordinate.

• Moving right along the x-axis, which increases the y-coordinate.

What is a square in terms of coordinates?

• A square is a quadrilateral with four equal sides and four right angles, represented by four points on a coordinate grid that are equidistant from each other.

• A square is a shape with four sides of different lengths and no right angles.

• A square is a polygon with three sides and three angles.

• A square is a figure that can only be represented in a three-dimensional space.

What does it mean to move 'east' on a coordinate grid?

• Moving left along the x-axis, which decreases the x-coordinate.

• Moving right along the x-axis, which increases the x-coordinate.

• Moving up along the y-axis, which increases the y-coordinate.

• Moving down along the y-axis, which decreases the y-coordinate.

What is the origin in a coordinate grid?

• The point where the x-axis and y-axis intersect, represented by the ordered pair (0, 0).

• The point where the x-axis meets the positive y-axis, represented by (0, 1).

• The point where the y-axis meets the negative x-axis, represented by (-1, 0).

• The point where the x-axis and y-axis are parallel, represented by (1, 1).

What is a coordinate grid?

• A one-dimensional line used for measuring distances.

• A two-dimensional plane formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis).

• A method for plotting points in three-dimensional space.

• A type of graph used only for statistical data.

What does it mean to move 'south' on a coordinate grid?

• Moving up along the y-axis, which increases the y-coordinate.

• Moving down along the y-axis, which decreases the y-coordinate.

• Moving left along the x-axis, which decreases the x-coordinate.

• Moving right along the x-axis, which increases the x-coordinate.

What is the x-axis?

• The vertical line on a coordinate grid where the x-coordinate is zero.

• The horizontal line on a coordinate grid where the y-coordinate is zero.

• The diagonal line on a coordinate grid that represents the slope.

• The line that separates the first and fourth quadrants of a coordinate grid.

How do you determine the fourth vertex of a rectangle given three vertices?

• Use the coordinates of the three given vertices to find the missing point that completes the rectangle.

• Calculate the area of the rectangle and use it to find the fourth vertex.

• Draw a diagonal between the two opposite vertices and find the midpoint.

• Use the Pythagorean theorem to determine the length of the sides.
