Which kind of function best models the data in the table? Graph the data and write an equation to model the data. x y 0 –2 1 –3 2 –4 3 –5 4 –6 linear; y = x – 2 quadratic; y = x2 – 2 linear; y = –x – 2 exponential; y = 3x – 2
The data in the table forms a linear relationship.
Here is the equation that models the data: y = -x - 2
And here is the graph of the data:
