answer all of them with an example
coordinate plane – a two-dimensional graph created when a horizontal number line intersects with a vertical number line
coordinates – a pair of numbers that indicates the position of a point in a coordinate plane, typically written as (x, y)
ordered pair – the point (x, y)
origin – the point (0, 0) where the x-axis and y-axis intersect
polygon – a closed figure with three or more straight sides, with no intersecting lines.
quadrilateral – a closed figure with four straight sides
quadrant – one of the four areas in the coordinate plane
triangle – a three-sided polygon
vertex – the point where two sides of a polygon meet forming an angle
x-axis – the horizontal number line on a coordinate plane
x-coordinate – the first number in an ordered pair
y-axis – the vertical number line on a coordinate plane
y-coordinate – the second number in an ordered pair
Example:
- In a coordinate plane, the point (3, 4) represents the coordinates of a point, where the x-coordinate is 3 and the y-coordinate is 4.
- The ordered pair (6, 2) represents a point on the coordinate plane.
- The origin of the coordinate plane is located at the point (0, 0).
- A quadrilateral is a figure with four straight sides, such as a square or rectangle.
- In the coordinate plane, quadrant II is the area to the left of the y-axis and above the x-axis.
- A triangle is a polygon with three sides, such as an equilateral triangle.
- The vertex of an angle in a polygon is the point where two sides meet.
- The x-coordinate of a point is the first number in an ordered pair, such as the x-coordinate in (5, -2) is 5.
- The y-axis is the vertical number line in a coordinate plane.
- The y-coordinate is the second number in an ordered pair, such as the y-coordinate in (-3, 8) is 8.
what about x-axis – the horizontal number line on a coordinate plane
x-coordinate – the first number in an ordered pair
Example:
- The x-axis is the horizontal line in a coordinate plane that intersects with the y-axis at the origin.
- The x-coordinate of a point in the coordinate plane is the first number in an ordered pair, such as the x-coordinate in (-2, 7) is -2.
