• both

• neither

The number of trees and the number of apples are given in the table above.  Determine which statement below is correct.

• The table is not proportional because the unit rate is not constant.

• The table is proportional and the unit rate is 1/13

• The table is proportional and the unit rate is 13.

• The table is not proportional because it doesn't pass through the origin.

Write an equation from the graph using (p) for price and (w) for weight.

• p = 20w

• w = 20p

• p = 20p

• w = 20w
