The correct question is:
The graph attached shows the number of points Derek scored
during his first five basketball games.
Write a multiplication equation and a division equation that compare the number of points Derek scored during Game 1 (x) to the number of points Derek scored during Game 4 (y).
Answer:
Multiplication equation is y = 3x
Division equation is x = y/3
Step-by-step explanation:
During Game 1, Derek had 6 points
Let x be this point, that is
x = 6
During Game 4, he had 18 points
Let y be this point, that is
y = 18
Notice that he has three times as many point in Game 4 as he had in Game 1. (Because 18 is 6 × 3)
This can be written mathematically as
18 = 6 × 3
y = x × 3 (where y is 18, and x is 6)
y = 3x (this is multiplication equation)
If you divide both sides by 3, we have
x = y/3 (this is the division equation)
