Answer:

Explanation:

To find the distance between each pair of points, you can use the distance formula, which is derived from the Pythagorean theorem.

Distance between -35 and 21 on a number line:

Simply subtract one number from the other:

Distance = 21 - (-35) = 21 + 35 = 56

Distance between points A (5, 0) and B (8, 0) in a 2D plane:

Since both points lie on the same horizontal line (the x-axis), the distance between them is simply the difference in their x-coordinates:

Distance = 8 - 5 = 3 units

Distance between points M (6, -2) and N (6, 8) in a 2D plane:

Since both points have the same x-coordinate, they lie on the same vertical line (the y-axis), so the distance between them is the difference in their y-coordinates:

Distance = 8 - (-2) = 8 + 2 = 10 units

Distance between points X (4, 4) and Y (9, 16) in a 2D plane:

Use the distance formula, which is the square root of the sum of the squares of the differences in x and y coordinates:

Distance = √((x₂ - x₁)² + (y₂ - y₁)²)

Distance = √((9 - 4)² + (16 - 4)²)

Distance = √(5² + 12²)

Distance = √(25 + 144)

Distance = √169

Distance = 13 units

So, the distances are:

56 units

3 units

10 units

13 units
