Plotting Coordinate Points

Front

What are coordinates?

Back

Coordinates are a set of values that show an exact position on a two-dimensional plane, typically represented as (x, y).

Front

What does the first number in an ordered pair represent?

Back

The first number in an ordered pair (x, y) represents the horizontal position (x-coordinate) on the Cartesian plane.

Front

What does the second number in an ordered pair represent?

Back

The second number in an ordered pair (x, y) represents the vertical position (y-coordinate) on the Cartesian plane.

Front

How do you plot the point (3, -2)?

Back

Start at the origin (0, 0), move right 3 units (positive x-direction), then move down 2 units (negative y-direction).

Front

What is the ordered pair for point A located 4 units right and 3 units up from the origin?

Back

(4, 3) is the ordered pair for point A.

Front

What is the ordered pair for point B located 5 units left and 2 units down from the origin?

Back

(-5, -2) is the ordered pair for point B.

Front

What quadrant is the point (-3, 4) located in?

Back

Point (-3, 4) is located in Quadrant II.

Front

What quadrant is the point (2, -5) located in?

Back

Point (2, -5) is located in Quadrant IV.

Front

What is the distance formula between two points (x1, y1) and (x2, y2)?

Back

The distance formula is d = √((x2 - x1)² + (y2 - y1)²).

Front

What is the midpoint formula between two points (x1, y1) and (x2, y2)?

Back

The midpoint formula is M = ((x1 + x2)/2, (y1 + y2)/2).
