Question

Find the distance between two points rounding to the nearest tenth if needed. (-5,4) and (4,-8)

Answer 1

d = 15

Explanation:

(-5, 4), (4, -8)

(x₁, y₁) (x₂, y₂)

d = √(x₂ - x₁)² + (y₂ - y₁)²

d = √(4 - (-5))² + (-8 - 4)²

d = √(4 + 5)² + (-12)²

d = √(9)² + (-12)²

d = √81 + 144

d = √225

d = 15
