Answer:
d ≈ 15.62
Explanation:
We know
L(-4,9) and M(8,-1)
Find the length of the bar.
We will use the distance formula d = √((x₂ - x₁)² + (y₂ - y₁)²)to solve this.
d = √((8 - (-4))² + (-1 - 9)²)
d = √((8 + 4)² + (-1 - 9)²)
d = √((12)² + (-10)²)
d = √(144 + 100)
d = √244
d ≈ 15.62
So. the answer is 15.62
