Find the value of the slope and explain what it means in context. Be careful with the units.The slope is

thousand.(Round to four decimal places as needed.)
Part 5
e. Explain why interpreting the value for the intercept does not make sense in this situation.
In this situation, the intercept would be the population of a state that had no millionaires. Since there are no states in the given data with no millionaires, the intercept would not make any sense.
In this situation, the intercept would be the population at which everyone in the state would be a millionaire. Since it is unreasonable to assume that everyone in the state is a millionaire, the intercept does not make any sense.
In this situation, the intercept would be the number of millionaires that live in a state with a population of zero. Since there would be no population in the state, then any number of millionaires besides zero would not make sense.
