If u thinking about the graph of this line, the line is coming down from 15,
which is in y-axis. x intercept represent when 0 money is left, how many game he had played. in graph, put y-axis as money line(15, 14, 13 ..), and x-axis as money that he loses each game(.50, 1.00, 1.50 . ..).

Hello!
The equation you gave:

shows how money is left (y) after playing x games. It looks like this

In order to find how much money is left after 7 games, we just plug x=7 into the equation:

The x-intercept is the value of x when y = 0. We just plug y=0 into the equation and solve for x:

So the x-intercept is 30. Its interpretation is "How many games can you play until the money you have left is zero?". The answer is 30 games.

I hope this helps!
