Unit 8 Review

Front

What are the coordinates of the vertices of a rectangle located at (0, -1), (0, 2), (-7, -1), and (-7, 2)?

Back

The vertices are (0, -1), (0, 2), (-7, -1), and (-7, 2).

Front

If point D is at (–3, 2) and is reflected across the x-axis, what are the coordinates of the reflected point?

Back

The reflected point is at (–3, -2).

Front

What is the name of the vertical axis in the coordinate plane?

Back

The vertical axis is called the y-axis.

Front

What is the distance between the points (42 1/4) and (47 1/2) on a coordinate grid?

Back

The distance is 5 1/4 units.

Front

What is the x-coordinate of the point (5, 3)?

Back

The x-coordinate is 5.

Front

What is the y-coordinate of the point (5, 3)?

Back

The y-coordinate is 3.

Front

In which quadrant is the point (–4, 5) located?

Back

The point (–4, 5) is located in quadrant II.

Front

What is the formula to calculate the distance between two points (x1, y1) and (x2, y2)?

Back

The distance formula is √((x2 - x1)² + (y2 - y1)²).

Front

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

Back

To reflect a point across the x-axis, you change the sign of the y-coordinate.

Front

What is the definition of a coordinate plane?

Back

A coordinate plane is a two-dimensional surface formed by the intersection of a vertical line (y-axis) and a horizontal line (x-axis).
