What is 4 feet to 20 inches written as a fraction

Part A. It is non linear because it can't make straight line.

Part B. In the graph▼

A is increasing,

B is Constant,

C is decreasing,

Part C. A is Increasing by the (0 to 16) because it is in upward and B is constant because it is (16 to 16) it is in same level then C is decreasing by the (16 to 0) because it is in downward.

I hope you understand
