Answer:
The missing value y=12.5 and we have (5,12.5)
Step-by-step explanation:
The formula used for direct variation is:
We need to find missing value (2,5)(5,y)
First we will find k, and then y
We have x=2, y=5
Find k:
Now, we cam find missing value in (5,y)
We have x=5, k=2.5 and y=?
So, the missing value y=12.5 and we have (5,12.5)
