Question #2061d

Answer 1

The number of players is not prorportional to the number of teams.

Explanation:

Let `x` the number of teams and let `y` the number of players.

Four teams have 19 players each, and the other `x-4` teams have 18 players each.

The number of total players is:
`y=19*4+18(x-4)`
`y=18x+4`

The graph of `y=18x+4` crosses the y-axis at `(0,4)` and the line does not pass the origin `(0,0)`. `y` is not proportional to `x`.

What is the point
If `y` is proportional to `x`, the fomula of the function must be `color(red)(y=ax)`. This is a special case for a linear function `color(blue)(y=ax+b)`.
