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). Each point on the plane is defined by an ordered pair of numbers (x, y).

Front

What does the ordered pair (x, y) represent?

Back

In an ordered pair (x, y), 'x' represents the horizontal position on the x-axis, and 'y' represents the vertical position on the y-axis.

Front

What is the x-axis?

Back

The x-axis is the horizontal line on a coordinate plane where the y-value is zero.

Front

What is the y-axis?

Back

The y-axis is the vertical line on a coordinate plane where the x-value is zero.

Front

How do you plot the point (3, 4)?

Back

Start at the origin (0, 0), move right 3 units along the x-axis, then move up 4 units along the y-axis.

Front

What is the distance between the points (2, 3) and (2, -1)?

Back

The distance is 4 units, as they share the same x-coordinate.

Front

What does a negative x-value indicate on a coordinate plane?

Back

A negative x-value indicates a position to the left of the origin on the x-axis.

Front

What does a negative y-value indicate on a coordinate plane?

Back

A negative y-value indicates a position below the origin on the y-axis.

Front

What is the origin in a coordinate plane?

Back

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

Front

How do you identify the quadrant of a point (x, y)?

Back

The quadrant is determined by the signs of x and y: Quadrant I (x>0, y>0), Quadrant II (x<0, y>0), Quadrant III (x<0, y<0), Quadrant IV (x>0, y<0).
