Answer:

d ≈ 12.0 units

Explanation:

calculate the distance d, using the distance formula

d =
\sqrt{(x_(2)-x_(1))^2+(y_(2)-y_(1))^2 }

let (x₁, y₁ ) = (4, 4 ) and (x₂, y₂ ) = (- 4, - 5 )

substitute these values into the formula for d

d =
√((-4-4)^2+(-5-4)^2)

=
√((-8)^2+(-9)^2)

=
√(64+81)

=
√(145)

≈ 12.0 units ( to the nearest tenth )
