Answer:
8 units
Step-by-step explanation:
The x coordinates don't change so you just subtract 2 from 10 to get the distance.
Answer:
8
Step-by-step explanation:
To calculate the distance d, using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = A(- 9, 2) and (x₂, y₂ ) = B(- 9, 10)
d = [tex]\sqrt{(-9+9)^2+(10-2)^2}[/tex]
= [tex]\sqrt{0^2+8^2}[/tex] = [tex]\sqrt{64}[/tex] = 8
