<u>Note</u>: The "point-slope form" of the equation of a line is:
→ " y − y₁ = m(x −x₁) " .
We are given the slope, m" , is: " - 3 " ;
We are given a point on the line [on the graph that is represented by this equation]; with the coordinates: " (-2 , 1) " ;
→ which is in the format: " (x₁ , y₁) " ;
→ As such: " x₁ = -2 " ; " y₁ = 1 " ;

As aforementioned, the equation of a line in "point-slope form" ; is:
_________________________________________________________
→ " y − y₁ = m(x − x₁) " ;
in which:
→ "(x₁ , y₁) " represents the coordinates of a given point on the [line of the graph represented by the equation] ; AND:
→ " m " = the slope of the line [represented by the equation] " ;
We proceed by substituting our known values for "m" ; "y₁" ; and "x₁" :
→ " y − 1 = - 3(x − (-2) ) " ;

→ Rewrite as:
_______________________________________________________
→ " y − 1 = - 3(x + 2) " ;
→ which is our answer; since it is written in "point-slope form" .

Answer:
x = 38
Step-by-step explanation:
3x-16+x+6+x = 180
5x -10 = 180
5x = 180 + 10
x = 190 / 5
x = 38
Its hard to explain how to solve but I could just give you the answer: 4.4
The mean would jump from $550 to $5550.
The median would jump from $550 to $5275.
Answer:
The correct option is B.
Step-by-step explanation:
It is given that there is a strong, negative, linear relationship between x and y. where, x is the number of consecutive hours a worker has been assembling chainsaws and y is the number of chainsaws he can produce in an hour.
He finds that 70%of the variation in chainsaws produced per hour can be explained by the regression of y on x.
The slope is -0.7, therefore option B is correct.
