Front

What is the distance between two points on a coordinate grid?

Back

The distance between two points (x1, y1) and (x2, y2) can be calculated using the formula: Distance = |y2 - y1| for vertical distance or |x2 - x1| for horizontal distance.

Front

How do you find the distance between points G and H if they are on the same vertical line?

Back

If points G and H are on the same vertical line, the distance is the absolute difference of their y-coordinates: Distance = |yH - yG|.

Front

What is the distance between points (3, -5) and (3, -8)?

Back

3 units.

Front

What is the distance between points (-3, 5) and (-3, -8)?

Back

13 units.

Front

What does the term 'coordinate plane' refer to?

Back

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

Front

What are the coordinates of a point?

Back

Coordinates of a point are a pair of numbers (x, y) that define its position on the coordinate plane.

Front

What is the x-axis?

Back

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

Front

What is the y-axis?

Back

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

Front

How do you calculate the distance between two points with the same x-coordinate?

Back

If two points have the same x-coordinate, the distance is the absolute difference of their y-coordinates: Distance = |y2 - y1|.

Front

What is the formula for calculating distance between two points in a coordinate plane?

Back

Distance = √((x2 - x1)² + (y2 - y1)²).
