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

Front

What does the first number in a coordinate (x, y) represent?

Back

The first number (x) represents the horizontal position of the point, indicating how far to move left or right.

Front

What does the second number in a coordinate (x, y) represent?

Back

The second number (y) represents the vertical position of the point, indicating how far to move up or down.

Front

How many quadrants are in a coordinate plane?

Back

There are 4 quadrants in a coordinate plane.

Front

What is Quadrant I?

Back

Quadrant I is the section of the coordinate plane where both x and y coordinates are positive.

Front

What is Quadrant II?

Back

Quadrant II is the section of the coordinate plane where x coordinates are negative and y coordinates are positive.

Front

What is Quadrant III?

Back

Quadrant III is the section of the coordinate plane where both x and y coordinates are negative.

Front

What is Quadrant IV?

Back

Quadrant IV is the section of the coordinate plane where x coordinates are positive and y coordinates are negative.

Front

How do you plot a point on a coordinate plane?

Back

To plot a point, start at the origin (0,0), move left or right according to the x-coordinate, and then move up or down according to the y-coordinate.
