Find the distance between the points (2, 8) and (-1, 9).

The distance is equal to 3.16

Step-by-step explanation:

To find the distance between the points (2, 8) and (-1, 9), we will follow the steps below;

First we need to write down the formula for finding distance between two points.

D = √(x₂ - x₁)² + (y₂ - y₁)²

From the question, the points given are;   (2, 8) and (-1, 9)

This implies that;  x₁ = 2      y₁ = 8        x₂=-1        y₂ = 9

We can now proceed to insert our values into the formula;

D = √(x₂ - x₁)² + (y₂ - y₁)²

D = √(-1 - 2)² + (9 - 8)²

D = √(-3)² + (1)²

D = √9 + 1

D = √10

D =3.16

The distance is equal to 3.16
