Points on Coordinate Planes

Front

What is a coordinate plane?

Back

A coordinate plane is a two-dimensional surface where points are defined by a pair of numbers (x, y). The horizontal line is called the x-axis, and the vertical line is called the y-axis.

Front

What does the first number in an ordered pair (x, y) represent?

Back

The first number (x) represents the horizontal position on the coordinate plane, indicating how far to move left or right from the origin.

Front

What does the second number in an ordered pair (x, y) represent?

Back

The second number (y) represents the vertical position on the coordinate plane, indicating how far to move up or down from the origin.

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 the point (3, 2) on a coordinate plane?

Back

Start at the origin (0, 0), move 3 units to the right along the x-axis, and then move 2 units up along the y-axis.

Front

What is the point (-2, -3) located?

Back

The point (-2, -3) is located 2 units to the left and 3 units down from the origin.

Front

What is the distance between the points (1, 1) and (1, 4)?

Back

The distance is 3 units, as they are on the same vertical line.

Front

What is the distance between the points (2, 3) and (5, 3)?

Back

The distance is 3 units, as they are on the same horizontal line.

Front

What does it mean if a point has a negative x-coordinate?

Back

A negative x-coordinate means the point is located to the left of the origin on the x-axis.

Front

What does it mean if a point has a negative y-coordinate?

Back

A negative y-coordinate means the point is located below the origin on the y-axis.
