Coordinate Plane

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). It is used to locate points using ordered pairs.

Front

What are ordered pairs?

Back

Ordered pairs are pairs of numbers used to represent the position of a point on a coordinate plane, written in the form (x, y).

Front

What does the x-axis represent?

Back

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

Front

What does the y-axis represent?

Back

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

Front

How many quadrants are in a coordinate plane?

Back

There are 4 quadrants in a coordinate plane.

Front

What is the first quadrant?

Back

The first quadrant is the section of the coordinate plane where both x and y coordinates are positive.

Front

What is the second quadrant?

Back

The second quadrant is the section of the coordinate plane where x coordinates are negative and y coordinates are positive.

Front

What is the third quadrant?

Back

The third quadrant is the section of the coordinate plane where both x and y coordinates are negative.

Front

What is the fourth quadrant?

Back

The fourth quadrant is the section of the coordinate plane where x coordinates are positive and y coordinates are negative.

Front

How do you reflect a point over the x-axis?

Back

To reflect a point (x, y) over the x-axis, change the sign of the y-coordinate, resulting in the point (x, -y).
