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

How do you find the perimeter of a polygon?

Back

To find the perimeter of a polygon, add the lengths of all its sides together.

Front

What is the difference between positive and negative numbers?

Back

Positive numbers are greater than zero, while negative numbers are less than zero. They are used to represent values below zero.

Front

What is the significance of the origin in a coordinate plane?

Back

The origin is the point (0, 0) on the coordinate plane where the x-axis and y-axis intersect. It serves as the reference point for all other points.

Front

What does it mean for a statement to be true or false in mathematics?

Back

In mathematics, a true statement is one that is correct based on mathematical principles, while a false statement is incorrect.

Front

How do you plot a point on the coordinate plane?

Back

To plot a point, start at the origin, move 'x' units along the x-axis, and then 'y' units up or down along the y-axis.

Front

What is the meaning of the term 'perimeter'?

Back

Perimeter is the total distance around the outside of a polygon, calculated by adding the lengths of all its sides.
