Asked by Latoyia

the length of a coil l (in centimeters) is a function of the weight w (in kilograms) applied to the coil. For a particular coil, the function is represented by the equation l=54-3w. Explain the meaning of the numbers 54 and -3 within the context of this problem.

54 is the length when there is no weight. -3 is the spring constant, ie, how much the length changes as a function of weight.
