Step-by-step explanation:
To find whether the rates are equivalent or not, we will use proportions.
[tex]\frac{126\text{ points}}{3\text{ games}}=\frac{210\text{ points}}{5\text{ games}}[/tex]
Let us simplify our fractions.
[tex]42\frac{\text{ points}}{\text{game}}=42\frac{\text{ points}}{\text{game}}[/tex]
We can see that both unit rates are same, therefore, the rates are equivalent and equal to 42 points per game.
