2. A company is growing a type of wheat that gains height at a constant rate. They know that its
height, h, can be found using the equation h=4.6w, where w is the number of weeks it has
been growing and the height is in centimeters.
They experiment by adding nutrients to a field to see if it will change the above equation. The
data below shows their results every four weeks.
(a) Create an equation for the height, h,
of the wheat that has been grown
with the nutrient added. Show your
work.

Height, h, cm

(b) Did adding the nutrient increase the rate at which the wheat grew? Explain.
