To determine the average points scored per game, you can divide the total points scored by the total number of games played.
From your information, the dot on the graph is at (number of games, total points scored) = (7, 210). This means 7 basketball games were played and 210 points were scored.
Now, calculate the average points per game:
\[ \text{Average points per game} = \frac{\text{Total points scored}}{\text{Total games played}} = \frac{210}{7} \]
\[ \text{Average points per game} = 30 \]
So, an average of 30 points were scored per game.
