Hi hi hi hi
Y=3x+6
y=mx+b 3 is slope and m is also the slope, six is b because it’s where it BEgins :)
If we know that 30% of the time is used after 9 minutes we can write this mathematically as:

By solving for x we can determine the total time allowed to play games and so:

The total time allowed to play games is 30 minutes. Since 9 minutes have lapsed 30-9=21 minutes left to play.
