Graphing points

Front

What is the coordinate plane?

Back

A two-dimensional surface where points are defined by pairs of numbers (x, y), representing horizontal and vertical positions.

Front

What are the x-axis and y-axis?

Back

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

Front

How do you graph the point (7, 1)?

Back

Start at the origin (0,0), move 7 units to the right on the x-axis, and then 1 unit up on the y-axis.

Front

What does an ordered pair represent?

Back

An ordered pair (x, y) represents a specific point on the coordinate plane, where 'x' is the horizontal position and 'y' is the vertical position.

Front

What is the significance of the origin in the coordinate plane?

Back

The origin is the point (0, 0) where the x-axis and y-axis intersect, serving as the reference point for all other points.

Front

What are negative coordinates?

Back

Negative coordinates indicate positions to the left of the origin on the x-axis or below the origin on the y-axis.

Front

How do you identify the quadrant of a point?

Back

The quadrant can be identified based on the signs of the coordinates: Quadrant I (positive, positive), Quadrant II (negative, positive), Quadrant III (negative, negative), Quadrant IV (positive, negative).

Front

What are the coordinates of point H if it is located at (-2, 4)?

Back

Point H is located 2 units left of the origin and 4 units up.

Front

What is the difference between the x-coordinate and y-coordinate?

Back

The x-coordinate indicates the horizontal position, while the y-coordinate indicates the vertical position of a point.

Front

How do you find the distance between two points on the coordinate plane?

Back

Use the distance formula: d = √((x2 - x1)² + (y2 - y1)²).
