find the slope and y intercept of line. (-11.6,15.8) and (-10/8,12.8)

  • Math -

    Those are not the line; they are the coordinates of two points ON the line, (x1,y1) and (x2,y2).

    The slope is m = (y2 -y1)/(x2-x1)

    Use either point to calculate b in the standard equation format
    y = mx + b

    I have a suspicion that the 10/8 you have written is supposed to be 10.8.
    Did you hit the wrong key?
