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).

Front

What are the x-axis and y-axis?

Back

The x-axis is the horizontal line on a coordinate plane, while the y-axis is the vertical line.

Front

What does it mean for lines to be parallel?

Back

Lines are parallel if they run in the same direction and never intersect.

Front

What does it mean for lines to be perpendicular?

Back

Lines are perpendicular if they intersect at a right angle (90 degrees).

Front

Which line is parallel to the x-axis?

Back

A line that runs horizontally is parallel to the x-axis.

Front

Which line is parallel to the y-axis?

Back

A line that runs vertically is parallel to the y-axis.

Front

What is the origin in a coordinate plane?

Back

The origin is the point where the x-axis and y-axis intersect, represented as (0, 0).

Front

How do you identify the coordinates of a point?

Back

Coordinates are written as (x, y), where x is the position on the x-axis and y is the position on the y-axis.

Front

What is the significance of the first quadrant in a coordinate plane?

Back

The first quadrant is where both x and y coordinates are positive.

Front

What is the significance of the second quadrant in a coordinate plane?

Back

The second quadrant is where x coordinates are negative and y coordinates are positive.
