Question

What is the distance between points (1, 9) and (9, -6

Answer 1

Answer:

17 units

Step-by-step explanation:

Calculate the distance d using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (1, 9) and (x₂, y₂ ) = (9, - 6)

d = $\sqrt{(9-1)^2+(-6-9)^2}$

   = $\sqrt{8^2+(-15)^2}$

   = $\sqrt{64+225}$

    = $\sqrt{289}$

    = 17
