Plotting & Reading Points

Front

What is the coordinate system used for plotting points?

Back

The Cartesian coordinate system, which consists of two perpendicular axes: the x-axis (horizontal) and the y-axis (vertical).

Front

How do you plot the point (-2, -6)?

Back

Move left 2 units on the x-axis and down 6 units on the y-axis.

Front

Which quadrant contains the point (4, -6)?

Back

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

Front

What does the first number in a coordinate pair represent?

Back

The x-coordinate, which indicates the horizontal position.

Front

What does the second number in a coordinate pair represent?

Back

The y-coordinate, which indicates the vertical position.

Front

What is the origin in a coordinate system?

Back

The point (0, 0) where the x-axis and y-axis intersect.

Front

How do you identify a point in the coordinate plane?

Back

By its coordinates (x, y), where x is the horizontal position and y is the vertical position.

Front

What is the significance of negative coordinates?

Back

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

Front

Which point is NOT like the rest: (-3, 5), (6, -2), (-1, 7), (-8, 9)?

Back

(6, -2) is the only point in Quadrant IV; the others are in Quadrants I and II.

Front

What letter corresponds to the coordinate (4, -6)?

Back

Z.
