PRACTICE QUESTIONS - Distance and Reflection

Front

What is the y-axis in a coordinate plane?

Back

The y-axis is the vertical line in a coordinate plane where the x-coordinate is 0.

Front

What is the x-axis in a coordinate plane?

Back

The x-axis is the horizontal line in a coordinate plane where the y-coordinate is 0.

Front

How do you find the distance between two points on a coordinate plane?

Back

Use the distance formula: Distance = √((x2 - x1)² + (y2 - y1)²).

Front

What happens to the coordinates of a point when it is reflected across the y-axis?

Back

The x-coordinate changes sign, while the y-coordinate remains the same.

Front

What is the distance between the points (3, 4) and (3, 1)?

Back

The distance is 3 units.

Front

What is the distance between the points (0, 0) and (4, 3)?

Back

The distance is 5 units.

Front

What is the vertical distance between two points with the same x-coordinate?

Back

The vertical distance is the absolute difference between their y-coordinates.

Front

What is the horizontal distance between two points with the same y-coordinate?

Back

The horizontal distance is the absolute difference between their x-coordinates.

Front

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

Back

The new coordinates are (2, -3).

Front

What are the coordinates of point B (4, -5) after it is reflected across the y-axis?

Back

The new coordinates are (-4, -5).
