    Answer:

    The distance between these two points is of 5 units.

    Step-by-step explanation:

    Distance between two points:

    Suppose that we have two points, (x_1,y_1) and (x_2,y_2). The distance between them is given by:

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

    In this question:

    Distance between  (-7,-1) and (-4,3). So

    D = \sqrt{(-4-(-7))^2+(3-(-1))^2} = \sqrt{3^2+4^2} = \sqrt{25} = 5

    The distance between these two points is of 5 units.
