2 answers:
<h2>Answer:</h2>
The probability is:
We know that the probability of an outcome is the number of favorable outcomes to the total number of outcomes.
The probability that she chooses you first ,and then chooses Kim second is given by:
( Since, firstly she needs to choose 1 student out of a total of 20 students and then she needs to choose 1 student i.e. kim out of the remaining 19 students )

Answer:
B. -3 1/2y + 2
Step-by-step explanation:
Our expression is: .
Let's first distribute out that parentheses. Remember that distribution is simply taking the sum of the product of the outside term with each of the inside terms. Here, the outside term is 1/2 and the inside terms are 4 and -2y:
Now, we have:
We want to combine like terms, which means combining all the terms with y in them:
Remember that -7/2 can be written as the mixed number -3 1/2, so our final answer is:
-3 1/2y + 2
The answer is thus B.

I think it would be b) because you're given a slope of 0, so that leaves you with
, resulting into this
You'd be just left with a continuous horizontal line going through the y-axis of 3 since you're passing the point (2,3), where 3 represents the y-value when your slope is at 0.
