PLZ HELP THANKS! Find the equation of the line passing through the pair points (-8,6) (-9,-9). The equation of the line in the f
timurjin [86]

Answer:

The answer is

<h2>15x - y = - 126</h2>

Step-by-step explanation:

To find the equation of the line we must first find the slope (m)

m =  \frac{y2 - y1 }{x2 - x1}

So the slope of the line using points

(-8,6) (-9,-9) is

m =  \frac{ - 9 - 6}{ - 9 + 8}  =  \frac{ - 15}{ - 1}  = 15

So the equation of the line using point (-8,6) and slope 15 is

y - 6 = 15( x + 8)

y - 6 = 15x + 120

Writing the equation in the form

Ax+By=C

We have

15x - y = -120-6

The final answer is

<h3>15x - y = - 126</h3>

Hope this helps you

kirill115 [55]

Answer:

The number of ways is  \left 9}\atop } \right. P _5 = 15120

Step-by-step explanation:

From the question we are told that

   The number of factories visited is  n = 9

    The number of factories to be visited by a representative  r = 5

The number of way to visit the 5 factories is mathematically represented as

         \left 9}\atop } \right. P _5 = \frac{9!}{(9-5)!}

Where P represents  permutation

  =>   \left 9}\atop } \right. P _5 = \frac{9 \ !}{4\ !}

 =>     \left 9}\atop } \right. P _5 = \frac{9 *8*7 * 6 * 5 * 4!}{4\ !}

=>    \left 9}\atop } \right. P _5 = 15120
