6th grade chapter 8 review

Front

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

Back

Distance = √((x2 - x1)² + (y2 - y1)²)

Front

What is the absolute value of a number?

Back

The absolute value of a number is its distance from zero on the number line, regardless of direction.

Front

What are coordinates in a Cartesian plane?

Back

Coordinates are a pair of numbers (x, y) that define a point's position on a two-dimensional plane.

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: (x, -y).

Front

What is the absolute value of ∣−5∣?

Back

5

Front

What is the distance between the points (-3, 4) and (-3, -3)?

Back

7 Units

Front

What letter corresponds to the coordinates (2, -4) in a grid?

Back

F

Front

What coordinates would you use to find the distance between two points?

Back

You would use both x-coordinates and y-coordinates.

Front

What is the formula for finding the midpoint between two points (x1, y1) and (x2, y2)?

Back

Midpoint = ((x1 + x2)/2, (y1 + y2)/2)

Front

What does it mean for a point to be in the first quadrant of a Cartesian plane?

Back

In the first quadrant, both x and y coordinates are positive.
