    La pendiente "m" de la recta que pasa por P1(x1, y1) y P2(x2; y2) es:

    . . . . y2 - y1

    m = -----------

    . . . . x2 - x1

    Entonces, la pendiente del lado ab es

    . . . . . . . -4 - 2 . . . -6

    m(ab) = ---------- = ------- = -3

    . . . . . . . 5 - 3 . . . . 2

    La pendiente del lado bc es

    . . . . . . . -2 - (-4) . . . 2

    m(bc) = ------------- = ------- = - 1/2

    . . . . . . . . 1 - 5 . . . . -4

    Por último, la pendiente del lado ac es:

    . . . . . . . -2 - 2 . . . . -4

    m(ac) = ------------ = ------- = 2

    . . . . . . . .1 - 3 . . . . -2

    RESPUESTA.

    ================

    PENDIENTE ab = -3

    PENDIENTE bc = -1/2

    PENDIENTE ac = 2

    ================

    Tienes que usar la ecuación de la pendiente:

    incremento de y entre incremento de x.
