Answer:
see explanation
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept)
given y + 2 = -
x + ![\frac{12}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B12%7D%7B7%7D)
Subtract 2 from both sides
y = -
x +
- ![\frac{14}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B14%7D%7B7%7D)
y = -
x -
← in slope- intercept form
Given are three married couples.
So, let us assume there are 3 men and 3 women
They are sitting in a row of 6 empty seats
There is a definite order constraint that each woman will sit left to her husband. The first woman gets 3 options to choose from 3 available seats. The second woman has two options left as already one seat is filled by the first woman. The last woman has one option left. So, it is ![3*2*1](https://tex.z-dn.net/?f=3%2A2%2A1)
So, number of ways is 3! =
= 6 ways.
