Parts of Functions

Front

What is the origin in a coordinate system?

Back

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

Front

What does the x-axis represent in a coordinate plane?

Back

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

Front

What does the y-axis represent in a coordinate plane?

Back

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

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to locate a point on a coordinate plane, written in the form (x, y).

Front

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

Back

The x-axis runs horizontally, while the y-axis runs vertically.

Front

How do you identify a point on a graph?

Back

A point is identified by its coordinates (x, y), where x is the position on the x-axis and y is the position on the y-axis.

Front

What is the significance of the point (5, 7) on a graph?

Back

The point (5, 7) is located 5 units to the right of the origin and 7 units up.

Front

What does it mean for a point to be on the x-axis?

Back

A point is on the x-axis if its y-coordinate is zero, represented as (x, 0).

Front

What does it mean for a point to be on the y-axis?

Back

A point is on the y-axis if its x-coordinate is zero, represented as (0, y).

Front

How can you determine 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).
