What is the point-slope form of a line that has a slope of –4 and passes through point (–3, 1)?
y minus (negative 3) = negative 4 (x minus 1)
y minus 1 = negative 4 left-bracket x minus (negative 3) right-bracket
Negative 1 minus y 1 = negative 4 (negative 3 minus x 1)
3 minus y 1 = negative 4 (1 minus x 1)

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
