Answer:
x=4, y=1
Step-by-step explanation:
x + 3y = 7
x - 3y = 1
Add the equations together to eliminate y
x + 3y = 7
x - 3y = 1
---------------------
2x = 8
Divide by 2
2x/2 = 8/2
x = 4
Subtract the two equations to eliminate x
x + 3y = 7
-x + 3y = -1
----------------------
6y = 6
Divide by 6
6y/6 = 6/6
y =1
Since the values are equally likely and equally spaced, their mean is the middle one.
the mean is 1/5
The variance is the average of the square of the deviations from the mean.
σ² = (1/3)((-1/10)² + 0² + (1/10)²) = 2/300
the variance is 2/300
we are given

For finding asymptote , we can find limit


now, we can solve it


so, horizontal asymptote is
.............Answer
Answer:

Step-by-step explanation:
There are multiple ways to solve this, but since two points are provided (8,7) and (7,p) and the slope is also given (m=4), we can use the formula for the slope.

Here,


Now we'll just solve for 'p'




Hence, the line passes through (8,7) and (7,3)
