Vladimir79 [104]

Answer:

  • See below

Step-by-step explanation:

For women, the initial number is 6, constant rate of change is w, number of years is x.

<u>Find the rate of change and work out the required formula:</u>

  • 10w + 6 = 391 ⇒ 10w = 385 ⇒ w = 38.5

<u>Formula:</u>

  • W(x) = 38.5x + 6

<u>Similarly for men, we get:</u>

  • 10m + 25 = 410 ⇒ 10m = 385 ⇒ m = 38.5

<u>Formula:</u>

  • M(x) = 38.5x + 25

(-1,-2) and (3, -162) a. Is there a line th(at goes through these two points? How do you know? If there is one, what is the equa
lana [24]

Answer:

The equation of line for given points is y = - 40 x - 42  

Step-by-step explanation:

Given two points as :

( -1 , - 2 )  and ( 3 , - 162 )

Now, Equation of line in points form

y - y_1 = m × ( x -  x_1 )

Where m is the slope of line

And, m = \frac{y_2 - y_1}{x_2 - x_1}

or, m = \frac{ - 162 + 2}{ 3 + 1}

or, m =  \frac{ - 160}{ 4}

∴   m = - 40

So, Slope of line for given points is - 40

Now equation of line can be written as

y - ( - 2 ) = ( - 40 ) × ( x -  ( - 1 ) )

or, y + 2 =  ( - 40 ) × ( x + 1 )

or, y + 2 = - 40 x - 40

or, y = - 40 x - 40 - 2

∴  y = - 40 x - 42        

Hence the equation of line for given points is y = - 40 x - 42    Answer
