Please please help!

Answer 1

Answer:

C

Step-by-step explanation:

Calculate the distance (d) using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (- 3, 9) and (x₂, y₂ ) = (3, 1)

d = $\sqrt{(3+3)^2+(1-9)^2}$

  = $\sqrt{6^2+(-8)^2}$

  = $\sqrt{36+64}$

  $\sqrt{100}$ = 10 → C
