option 2 you have 1 hour of homework at the start, then amount of homework duobles every week.

As per given by the question,
There are given that to the construct of equation to reperesent the number of hours of home work.
Now,
Here, y for the total hours and x for the total weeks.
The,
From option two;
In starting, you have 1 hours of homework, then after that amount of homework double in every week.
So,
Total hours of homework is 1,
Then , y is represent the 1 hour of homework.
Now,
The amount of home work double in every week,
So,
[tex]2y[/tex]Here, x represent the week.
So, homework double in every week.
Hence, the equation is;
[tex]x=2y[/tex]
