Coordinate Plane Review

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). Each point on the plane is defined by an ordered pair of numbers (x, y).

Front

What are the four quadrants of the coordinate plane?

Back

The four quadrants are: 1st Quadrant (x > 0, y > 0), 2nd Quadrant (x < 0, y > 0), 3rd Quadrant (x < 0, y < 0), 4th Quadrant (x > 0, y < 0).

Front

What does the ordered pair (x, y) represent?

Back

The ordered pair (x, y) represents the position of a point on the coordinate plane, where 'x' is the horizontal distance from the origin and 'y' is the vertical distance from the origin.

Front

How do you identify the quadrant of a point (x, y)?

Back

To identify the quadrant, check the signs of x and y: 1st Quadrant (both positive), 2nd Quadrant (x negative, y positive), 3rd Quadrant (both negative), 4th Quadrant (x positive, y negative).

Front

What are the coordinates of the origin?

Back

The coordinates of the origin are (0, 0).

Front

What is the x-axis?

Back

The x-axis is the horizontal line on the coordinate plane where y = 0.

Front

What is the y-axis?

Back

The y-axis is the vertical line on the coordinate plane where x = 0.

Front

What is the significance of the point (0, 0)?

Back

The point (0, 0) is called the origin and serves as the reference point for the coordinate plane.

Front

How do you plot a point on the coordinate plane?

Back

To plot a point (x, y), start at the origin, move 'x' units along the x-axis, and then 'y' units up (if positive) or down (if negative) along the y-axis.

Front

What is the distance between the points (3, 4) and (3, -2)?

Back

The distance is 6 units, calculated as |4 - (-2)| = 6.
