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 (x, y).

Front

What are the axes in a coordinate plane?

Back

The x-axis is the horizontal line, and the y-axis is the vertical line. They intersect at the origin (0,0).

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 coordinates (0,0).

Front

How many quadrants are in a coordinate plane?

Back

There are four quadrants in a coordinate plane, numbered counterclockwise starting from the upper right quadrant.

Front

What are the coordinates of a point in Quadrant 1?

Back

In Quadrant 1, both x and y coordinates are positive. For example, (3, 4) is in Quadrant 1.

Front

What are the coordinates of a point in Quadrant 2?

Back

In Quadrant 2, the x coordinate is negative and the y coordinate is positive. For example, (-3, 4) is in Quadrant 2.

Front

What are the coordinates of a point in Quadrant 3?

Back

In Quadrant 3, both x and y coordinates are negative. For example, (-3, -4) is in Quadrant 3.

Front

What are the coordinates of a point in Quadrant 4?

Back

In Quadrant 4, the x coordinate is positive and the y coordinate is negative. For example, (3, -4) is in Quadrant 4.

Front

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

Back

To reflect a point (x, y) over the x-axis, keep the x coordinate the same and change the sign of the y coordinate. The reflected point is (x, -y).

Front

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

Back

To reflect a point (x, y) over the y-axis, change the sign of the x coordinate and keep the y coordinate the same. The reflected point is (-x, y).
