    The linear equation of relating two objects can be written in the form,

    y = ax + b

    Our x is the number of passenger and y is the weight (in tons). Using the first two conditions,

    10 = 60 (a) + b

    13 = 84 (a) + b

    The values of a and b from the equations are 0.125 and 2.5.

    For 50-passenger bus,

    y = (50) (0.125) + 2.5

    The value of y is 8.75.
