Question

The distance AB rounded to the nearest tenth =

Answer 1

Answer: 4.5

Explanation:

• A = (x₁, y₁) = (3, 1)
• B = (x₂, y₂) = (-1, -1)

Use the formula provided to find the distance:

`d=\sqrt{(x_(2)-x_(1))^(1)+(y_(2)-y_(1))^(2) } \\\\=\sqrt{(-1-3)^(2)+(-1-1)^(2)} \\\\=\sqrt{(-4)^(2)+(-2)^(2)} \\\\=√(16+4) \\\\=√(20) =4.47213595...`
