    Answer:

    Step-by-step explanation:

    The formula for finding the midpoint of two coordinates is expressed as;

    M(X,Y) = (\frac{x_1+x_2}{2} , \frac{y_1+y_2}{2})

    Given the coordinates c(-4,5) and d(-1,-4), x1 = -4, y1 = 5, x2 = -1 and y2 = -4.

    For the X coordinate of the midpoint

    X = x1+x2/2

    X = -4+(-1)/2

    X = -4-1/2

    X = -5/2

    X = -2.5

    Similarly for Y:

    Y = y1+y2/2

    Y = 5+(-4)/2

    Y = 5-4/2

    Y = 1/2

    Y = 0.5

    Hence the midpoint coordinate of C(-4,5) and D (-1,-4) is (-2.5, 0.5)
