(-1,4)(2,3)
slope = (3-4) / (2-(-1) = -1/3....a parallel line will have the same slope
y = mx + b
slope(m) = -1/3
(4,-2)...x = 4 and y = -2
now we sub
-2 = -1/3(4) + b
-2 = - 4/3 + b
-2 + 4/3 = b
-6/3 + 4/3 = b
-2/3 = b
equation in slope int form is : y = -1/3x - 2/3
y = -1/3x - 2/3
1/3x + y = - 2/3...multiply by 3
x + 3y = - 2
x + 3y + 2 = 0 <== general form
Answer:
Number of apartment = 9
Step-by-step explanation:
Given the ANOVA result :
ANOVA ____ df ____ SS
Regression __ 1 ___ 41587.1
Residual ____ 7 ___
Total _______ 8 __ 51984.5
Number of apartment building in sample (n) :
Degree of freedom (df) = n - 1
The degree of freedom = total = 8
Hence,
8 = n - 1
8 + 1 = n - 1 + 1
9 = n
Hence, number of apartment building in sample = 9
Answer:
x = sqrt (22)
Step-by-step explanation:
This is a RIGHT triangle with the two legs of equal length sqrt 11
us pythagorean theorem
a^2 + b^2 = c ^2 where a and b are the legs and c = hypotenuse
(sqrt11)^2 + (sqrt11)^2 = x^2
11 + 11 = x^2
x = sqrt (22)
