Answer:
Plot (-9,5) then you do rise over run and go down 2 and to the right 3
Step-by-step explanation:
So your points would be (-9,5) and(-6,3)
Yes they can just think of numbers with opposite signs
I-5I=I+5I the absoulte value is 5
Answer:




Step-by-step explanation:
The probability mass function P(X = x) is the probability that X happens x times.
When n trials happen, for each
, the probability mass function is given by:

In which p is the probability that the event happens.
is the permutation of n elements with x repetitions(when there are multiple events happening(like one passes and two not passing)). It can be calculated by the following formula:

The sum of all P(X=x) must be 1.
In this problem
We have 3 trials, so 
The probability that a wafer pass a test is 0.7, so 
Determine the probability mass function of the number of wafers from a lot that pass the test.
