Help please super lost please I’d love some help

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 ) = (- 10, 5) and (x₂, y₂ ) = (- 2, - 10)
d = [tex]\sqrt{(-2+10)^2+(-10-5)^2}[/tex]
= [tex]\sqrt{8^2+(-15)^2}[/tex]
= [tex]\sqrt{64 +225}[/tex]
= [tex]\sqrt{289}[/tex]
= 17
