Big points For this and I will mark brainliest for the first answer The team bus is carrying 15 players. Only sophomores, juniors, and seniors are on the team bus. There is one more sophomore than juniors. The number of seniors is one more than the sum of the number of juniors and sophomores. How many juniors are there?

27

Step-by-step explanation:

27 because they are the one in the team bus

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
