Answer:
y=1/2x-6
Step-by-step explanation:
y-y1=m(x-x1)
y-(-1)=1/2(x-10)
y+1=1/2x-10/2
y=1/2x-5-1
y=1/2x-6
1 . the answer is wrong . correct answer is 3,531.33
2. I would give you suggestions that you need to work on your calculations skills
Domain is all the values that x can take in the function f(x).
Here, y = x^2
or y = f(x) = x^2
here, x can take any real value. So all real numbers are the domain of f(x).
Domain of y = R
R mean real numbers.
The number of days that the eggs took in hatching is 54 days.
Given that mean is 50, standard deviation is 2 and confidence level is 95% and sample size is 35.
We are required to find the number of days it took to hatch the eggs.
We have to apply the z statistics because sample size is greater than 30.
Z=(X-μ)/σ, in which μ is mean and σ is standard deviation.
Z score for the confidence level 95% is 1.96.
1.96=(X-50)/2
3.92=X-50
X=50+3.92
X=53.92
X=54 (After approximation)
Hence the number of days that the eggs took in hatching is 54 days.

Answer:
Perpendicular lines have slope that are negative reciprocals.
The slope of the perpendicular line is M = -1/3.
Step-by-step explanation:
(4,-1) --> X = 4, Y = -1, M = -1/3
y = Mx + b
-1 = (-1/3)*4 + b
-1 = (-4/3) + b
-3/3 = (-4/3) + b
-3 = -4 + 3b
1 = 3b
b = 1/3
y = (-1/3)X + 1/3
