Solve the following problems to test your understanding of linea relationships, inverse variation, the correlation coefficient, and standard
deviation. These problems are about a park with a small farm, a train, and
a snack bar.
1. This table shows the growth of one pig raised on the farm.

a. Make a graph of the (age, weight) data. Draw a line that
fits the data.
b. Find a linear equation in the form y = mx + b for the line
in part (a).
c. What do the values of m and b in your equation tell you about
the pig's growth?
d. Use your equation to estimate the pig's weight at 3.5 months
and at 7 months.
