Answer:
AB = 2[tex]\sqrt{2}[/tex]
Step-by-step explanation:
Calculate the length using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = A(- 3, - 4) and (x₂, y₂ ) = B(- 1, - 6)
AB = [tex]\sqrt{(-1+3)^2+(-6+4)^2}[/tex]
= [tex]\sqrt{2^2+(-2)^2}[/tex]
= [tex]\sqrt{4+4}[/tex]
= [tex]\sqrt{8}[/tex] = 2[tex]\sqrt{2}[/tex] ≈ 2.83 ( to 2 dec. places )
Answer:
Step-by-step explanation:
AB= √((-6+4)²+(-1+3)²)² = √(4+4)= √8 =2√2
