Make a scatterplot for each set of data. Tell whether the data show a linear association or a nonlinear association.
\((1,\ 2),\ (7,\ 9.5),\ (4,\ 7),\ (2,\ 4.2),\ (6,\ 8.25),\ (3,\ 5.8),\ (5,\ 8),\ (8,\ 10),\ (0,\ 0)\)

Step 1
Scatterplot
The first coordinate x in an ordered pair (x,y) is on the horizontal axis, while the second coordinate y is on the vertical axis.
The 2-values range from 0 to 8, thus an appropriate scale for the horizontal axis is from —1 to 9.
The y-values range from 0 to 10, thus an appropriate scale for the vertical axis is from —1 to 11.

Step 2
We note that there is a slight curvature present in the scatterplot and thus the data show a nonlinear association.
Result:
Nonlinear assotiation.
