Answer:

AB = [tex]\sqrt{34}[/tex]

Step-by-step explanation:

Calculate the distance d using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = A(- 2,  1) and (x₂, y₂ ) = B(3, 4)

d = [tex]\sqrt{(3+2)^2+(4-1)^2}[/tex]

   = [tex]\sqrt{5^2+3^2}[/tex]

  = [tex]\sqrt{25+9}[/tex]

   = [tex]\sqrt{34}[/tex]
