Answer:
AB = 5 units
Step-by-step explanation:
Calculate the distance d using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = A (2, 2 ) and (x₂, y₂ ) = B (- 2, - 1 )
AB = [tex]\sqrt{(-2-2)^2+(-1-2)^2}[/tex]
= [tex]\sqrt{(-4)^2+(-3)^2}[/tex]
= [tex]\sqrt{16+9}[/tex]
= [tex]\sqrt{25}[/tex]
= 5
