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 coordinates of a point?

Back

Coordinates of a point are a pair of numbers (x, y) that define its position on the coordinate plane.

Front

What does the x-axis represent?

Back

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

Front

What does the y-axis represent?

Back

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

Front

What is the origin in a coordinate plane?

Back

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

Front

How do you plot a point on the coordinate plane?

Back

To plot a point, start at the origin, move along the x-axis to the x-coordinate, and then move vertically to the y-coordinate.

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they never intersect and have the same slope.

Front

What does it mean for two lines to be perpendicular?

Back

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

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.
