We know
in the graph two points
point 1 (2,1) and point 2 (-1,-4)
the equation in point-slope form is ----------------> (y-y1)=m(x-x1)
step 1
find the value of m
m=(y2-y1)/(x2-x1)----------> (-4-1)/(-1-2)--------> m=5/3
step 2
with the point (-1,-4) and m=5/3
find the equation in point-slope form
(y-(-4))=(5/3)*(x-(-1))-------------> (y+4)=(5/3)(x+1)
the answer is the option d) ( y+ 4 ) =+ 5/3 ( x + 1 )

Variance

Step-by-step explanation:</h2>
The standard deviation is related to the variance. The standard deviation measures the variation or dispersion of a set of data and is represented by the Greek letter sigma 
, while the variance measures how far a set of numbers are spread out from their average value. The variance is obtained by squaring the standard deviation, so the variance can be found as 
It says to estimate first 1,537 turns to 2,000 because the 5 is 5 or more so the 1 becomes 2 and everything else is zeros. Now multiply 2000x 242=484,000 is the Estimation. Now find the correct product for 1,537x242=371,954
Answer:
Simplifying
(4x + -6) = (x + 6y)
Reorder the terms:
(-6 + 4x) = (x + 6y)
Remove parenthesis around (-6 + 4x)
-6 + 4x = (x + 6y)
Remove parenthesis around (x + 6y)
-6 + 4x = x + 6y
Solving
-6 + 4x = x + 6y
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-1x' to each side of the equation.
-6 + 4x + -1x = x + -1x + 6y
Combine like terms: 4x + -1x = 3x
-6 + 3x = x + -1x + 6y
Combine like terms: x + -1x = 0
-6 + 3x = 0 + 6y
-6 + 3x = 6y
Add '6' to each side of the equation.
-6 + 6 + 3x = 6 + 6y
Combine like terms: -6 + 6 = 0
0 + 3x = 6 + 6y
3x = 6 + 6y
Divide each side by '3'.
x = 2 + 2y
Simplifying
x = 2 + 2y
