We will see that we have a direct variation, which can be written as:
y = 5x.
Do the data in the table represent a direct variation or an inverse variation?
Here we have the table:
x y
1 5
3 15
4 20
7 35
As you can see, as x increases, the other variable also increases. So we have a direct variation.
The general direct variation is:
y = k*x
If we use any pair of the table, like the second one (3, 15), we can write:
15 = k*3
Solving for k, we get:
15/3 = k = 5
Then the direct variation is:
y = 5*x
