In the figure shown de = 7x-13 and df =3x+3 what is the length of df?

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

Ade and abc are similar. which best explains why the slope of the line between points a and d is the same as the slope between points a and b?
