Answer:
Step-by-step explanation:
Since, the graph of the function is a straight line, function defining this function will be a linear function.
Let the equation of the line is,
y = mx + b
where m = slope of the line
b = y-intercept
From the graph,
b = 2
And two points (0, 2) and (-2, 1) lie on this line.
Slope 'm' = 
= 
= 
Now the equation will be,
y = 
Slot A = chairperson position
Slot B = secretary position
Slot C = treasurer position
There are 9 choices for slot A. After picking that person, there are 8 choices for slot B. Then 7 choices for slot C
Multiply those values out: 9*8*7 = 72*7 = 504
There are 504 ways to pick three people from a pool of nine.
Answer: 504
Note: order matters so this is a permutation. You can use the nPr permutation formula with n = 9 and r = 3 to get the same answer
-13 -23 because divide by two then add five and subtract 5
Last option
-2 is ur answer
