So,
These are actually special cases.
x = -6
No matter what value we substitute for y, x will always be -6.
These are some solutions to it:
(-6, 0)
(-6, -2)
(-6, 50)
Now, we know that:
But the run is zero, because the line is vertical. And dividing by zero is not allowed. Therefore, the slope of the line x = -6 is undefined.
y = 6
This is basically the same type as the previous one, with one exception.
Some solutions:
(0, 6)
(-47, 6)
(59, 6)
No matter what value we substitute for x, y will always be 6.
Remembering what the slope is equal to, we quickly see that since the rise is zero, and the denominator is infinite, we can conclude that the slope is zero.

Answer:
And using the probability mass function we can find the individual probabilities:
And replacing we got:
Then the probability that at least 2 disapprove of daily pot smoking is 0.4366
Step-by-step explanation:
Let X the random variable of interest "number of seniors who disapprove of daily smoking ", on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
And we want to find this probability:
And using the probability mass function we can find the individual probabilities:
And replacing we got:
Then the probability that at least 2 disapprove of daily pot smoking is 0.4366
