    Answer:

    \sqrt{34}

    Step-by-step explanation:

    Calculate the distance (d) using the distance formula

    d = √ (x₂ – x₁ )² + (y₂ – y₁ )²

    with (x₁, y₁ ) = (- 1, 2) and (x₂, y₂ ) = (2, 7)

    d = \sqrt{(2+1)^2+(7-2)^2}

      = \sqrt{3^2+5^2}

      = \sqrt{9+25} = \sqrt{34} ← exact distance
