The distance between the two points is 6.85 units.
How to find the distance between the two points?
To find the distance between two points (x₁, y₁) and (x₂, y₂), we use the formula:
d = √( (x₁ - x₂)² + (y₁ - y₂)²)
We have the points (-1,-2) and (-4,-8), replacing these values we will get the distance:
d = √( (-1 + 4)² + (-2 + 8)²)
d = √( 9 + 36)
d = √(47) = 6.85
