The variable y varies directly with x. When x = 35, y =5. What is the constant of variation (k)?

Question

Just type the value of k. If it's an integer, type the integer. If it's a fraction, write the fraction in simplest form. Do not write the number as a decimal.

Answer 1

"y varies directly as x" means that y = kx, for some constant, k.  

 

k is called the constant of variation

 

Substituting in the given values, we have 5 = 35k.

 

So, k = 1/7
