Chapter 5 - Linear Functions - 5-2 Direct Variation - Practice and Problem-Solving Exercises - Page 297: 30



Work Step by Step

Since the general form of a direct variation is y=kx, lets substitute the value of y and x into this equation: 1/2=3k (Divide both sides by 3) 1/6=k Now lets plug this value of k into the standard form of a direct variation: y=1/6x So, this is our equation that relates x and y in this problem.
