The random variable x is the number of occurrences of an event over an interval of ten minutes. it can be assumed that the probability of an occurrence is the same in any two-time periods of an equal length. it is known that the mean number of occurrences in ten minutes is 5.3. the appropriate probability distribution for the random variable

If f(x) =3x-2 and g(x) =2x+1 fins (f+ g) (x)

Write the point-slope form of the line passing through (2, -12) and parallel to y=3x.
