find the equation, in function form, of athe line that passes through the points(1/2,-3) and (7/6,5/9)

  • math -

    find slope
    slope = (5/9 + 3)/(7/6 - 1/2)
    = (32/9) / (2/3)
    = (32/9)(3/2) = 16/3

    so y =(16/3)x + b
    sub in the "easier" of the two points, (1/2 , -3)

    -3 = (16/3)(1/2) + b
    -3 = 8/3 + b
    b = -17/3

    y = f(x) = (-16/3)x - 17/3
