I love math and you will too!
Think of it like this
Rubber plantations <------ Tire manufacturer --------> Tire shop
Backward linkage Forward linkage
Because of the factory making tires, a backward linkage is an increase in the output and demand for rubber from the plantations since it is required to make tires.
A forward linkage is a business that increases output and supply because of the end product created by the manufacturer.
Hopefully that will help you choose the right answer.
