Plotting Points

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 does the x-axis represent on a coordinate plane?

Back

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

Front

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

Back

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

Front

How do you plot the point (3, 5)?

Back

Start at the origin (0, 0), move right 3 units (x-coordinate), then move up 5 units (y-coordinate).

Front

What is the origin on a coordinate plane?

Back

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

Front

If a point has coordinates (4, -2), where is it located?

Back

It is located 4 units to the right of the origin and 2 units down.

Front

What is the first number in an ordered pair called?

Back

The first number is called the x-coordinate.

Front

What is the second number in an ordered pair called?

Back

The second number is called the y-coordinate.

Front

How do you identify the coordinates of a point on a graph?

Back

Locate the point, then read the x-coordinate from the x-axis and the y-coordinate from the y-axis.

Front

What does it mean if a point is on the x-axis?

Back

If a point is on the x-axis, its y-coordinate is 0.
