    Answer:

    The distance between the two points is about 7.1 units.

    Step-by-step explanation:

    We want to find the distance between the two points (-3, 6) and (2, 1).

    To find the distance between any two points, we can use the distance formula:

    \displaystyle d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

    Let (-3, 6) be (x₁, y₁) and (2, 1) be (x₂, y₂). Substitute:

    \displaystyle d=\sqrt{((2)-(-3))^2+((1)-(6))^2}

    Simplify:

    \displaystyle d=\sqrt{(5)^2+(-5)^2}

    Evaluate:

    d=\sqrt{25+25}=\sqrt{25(2)}=5\sqrt{2}\approx 7.1\text{ units}

    The distance between the two points is about 7.1 units.
