Final answer:
To find the number of games in which Jana scored 2 goals this season, subtract the number of games in which she scored 0 or 1 goal from the total number of games. Set up the equation x + 38 = y to represent the number of games in which she scored 2 goals. The number line representation is 0, 1, 2, 3, ..., y - 38.
Step-by-step explanation:
To find the number of games in which Jana scored 2 goals this season, we need to subtract the number of games in which she scored 0 or 1 goal from the total number of games. Jana scored 0 goals in 22 games and 1 goal in 16 games, which gives us a total of 38 games where she scored either 0 or 1 goal. So, the number of games in which Jana scored 2 goals is the difference between the total number of games and 38.
If we let x be the number of games in which Jana scored 2 goals, we can set up the following equation: x + 38 = total number of games. Since the total number of games is not given, we can only represent it as a variable, let's say, y. So, we have the equation x + 38 = y.
Therefore, the best number line representation for all the possible numbers of games in which Jana scored 2 goals this season is:
0, 1, 2, 3, ..., y - 38
