Answer:
C)
Step-by-step explanation:
Given:
Number of freshmen = 3
Number of sophomores =3
Number of juniors =3
Number of seniors = 3
The team's captain is randomly selected from any grade level.
To find the the probability that a freshman will not be selected as captain.
Solution:
Total number of members in the team =
= 12
Probability that a freshman will be selected as captain will be:
⇒ 
⇒ 
Reducing to simple fraction by dividing numerator and denominator by 3.
⇒ 
⇒ 
Thus, probability that a freshman will not be selected as captain will be given as:
⇒ 
Taking LCD.
⇒ 
Subtracting the numerators.
⇒
(Answer)
Firstly, we need to understand the formula of point-slope form:

Where x and y is the coordinates and m is the slope respectively.
To find the slope:

In this case:

We can then put the above slope and the point (-1,4) into the formula:
4-y = -1/2(-1-x)
-y = 1/2+1/2x-4
y = -1/2x+7/2
Alternatively:
y-4=-1/2(x-(-1))
y=-1/2x-1/2+4
y = -1/2x+7/2
Therefore the answer is y = -1/2x+7/2.
