Question 1152702: Scientists are conducting an experiment with a gas in a sealed container. The mass of the gas is measured, and the scientists realize that the gas is leaking over time in a linear way. Its mass is leaking by 9.8 grams per minute. Seven minutes since the experiment started, the remaining gas had a mass of 392 grams.
Let x be the number of minutes that have passed since the experiment started, and let y be the mass of the gas in grams at that moment. Use a linear equation to model the weight of the gas over time.

You can put this solution on YOUR website! .
When you write in your post " . . . let y be the mass of the gas in grams at that moment", which EXACTLY moment do you mean ?
The moment when experiment started, OR the moment " . . . x minutes since the experiment started" ?
From the post, it is UNCLEAR to me . . .
