Plotting Points on the Coordinate Plane

Front

What is the coordinate plane?

Back

A two-dimensional surface formed by the intersection of a horizontal number line (x-axis) and a vertical number line (y-axis).

Front

What are the four quadrants of the coordinate plane?

Back

Quadrant I (positive x, positive y), Quadrant II (negative x, positive y), Quadrant III (negative x, negative y), Quadrant IV (positive x, negative y).

Front

What does the x-axis represent?

Back

The horizontal number line in the coordinate plane where the y-coordinate is zero.

Front

What does the y-axis represent?

Back

The vertical number line in the coordinate plane where the x-coordinate is zero.

Front

What is an ordered pair?

Back

A pair of numbers (x, y) that represent a point on the coordinate plane.

Front

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

Back

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

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.

Front

What quadrant is point (5, -4) located in?

Back

Quadrant IV, where x is positive and y is negative.

Front

How do you identify the coordinates of a point on the coordinate plane?

Back

The first number in the ordered pair indicates the horizontal position (x-coordinate), and the second number indicates the vertical position (y-coordinate).

Front

What is the distance from the origin to the point (4, 3)?

Back

The distance can be calculated using the Pythagorean theorem: √(4² + 3²) = √(16 + 9) = √25 = 5.
