the table shows the number of employees and number of active customer accounts for some different marketing companies

If this is the table,
Then a linear model would be the best fit.
y = 5x would represent this model.
How do we know this?
Let x be the number of employees and y be the number of active customer accounts then,
Just plug in x =1, to get y = 5.
Plug in x = 2, to get y = 10.
Plug in x = 10, to get y = 50.
So, we have a linear model with lowest residual error.
A linear model has a fixed common difference, or a fixed rate of change.
Any table which is given, just check out if there is a common difference. A common difference means linear model. A common ratio means exponential model. The table will be either of that.
