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.
