6th grade graphing review

Front

What is the x-axis?

Back

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

Front

What is the y-axis?

Back

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

Front

How do you reflect a point across the x-axis?

Back

To reflect a point (x, y) across the x-axis, change the sign of the y-coordinate to get (x, -y).

Front

What are coordinates?

Back

Coordinates are a set of values that show an exact position on a graph, typically written as (x, y).

Front

What does the point (0, 0) represent?

Back

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

Front

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

Back

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

Front

What is the first number in a coordinate pair?

Back

The first number in a coordinate pair is the x-coordinate, which indicates the horizontal position.

Front

What is the second number in a coordinate pair?

Back

The second number in a coordinate pair is the y-coordinate, which indicates the vertical position.

Front

If a point is at (5, -3), where is it located?

Back

The point (5, -3) is located 5 units to the right and 3 units down from the origin.

Front

What does it mean to reflect a point across the y-axis?

Back

To reflect a point (x, y) across the y-axis, change the sign of the x-coordinate to get (-x, y).
