sorry if its wrong this isn't my strong suit
Answer:
y = 2x - 3
Step-by-step explanation:
Slope-intercept form is y = mx + b
m = slope
b = y-intercept
If you look at the graph, the y-intercept is on (0, -3) which means the y-intercept is -3.
If you look at the slope, you can use the rise/run method. Let's use 2 as an example. We would turn it into a fraction, 2/1. You then want to use the rise/run method. Starting from the y-intercept, go up the amount of the first number, and then go right the amount of the second number. So we would go up 2 and 1 right.
So this is our answer, y = 2x - 3
I believe you are asking in how many ways they can sit. If so:
The 1st can sit anywhere: he has only 1 way to sit
The 2nd can sit in 11 ways, since one seat is already occupied
The 3rd can sit in 10 ways, since 2 seat are already occupied
The 4th can sit in 9 ways, since 3 seat are already occupied
The 5th can sit in 8 ways, since 4 seat are already occupied
--------------------------------------------------------------------------------
The 12th can sit in 1 way, since11 seat are already occupied
General formula for a circular table:
Number of ways they n persons can be seated: (n-1)!
and the 12 can be seated in (12-1)! = 11! = 39,916,800 ways.
This is called circular permutation
width = w
length = w +2
perimeter = 2L + 2w
40 = 2(w+2) + 2w
40 = 2w+4 +2w
40 = 4w+4
36=4w
w=36/4 = 9
with = 9
length = 9+2 = 11
area = l x w = 9*11 = 99 square cm
