To find the distance between two points (x1, y1) and (x2, y2) in a coordinate plane, we can use the distance formula:
Distance = √((x2 - x1)² + (y2 - y1)²)
Using the given points, we have:
Distance = √((-1 - 8)² + (-2 - (-4))²)
Simplifying inside the square root, we get:
Distance = √((-9)² + 2²)
Distance = √(81 + 4)
Distance = √85
Using a calculator or rounding, we can approximate the distance to the nearest tenth:
Distance ≈ 9.2 (to the nearest tenth)
