# Chapter 5 - Linear Functions - 5-2 Direct Variation - Lesson Check - Page 304: 1

yes; 3=k

#### Work Step by Step

Direct variation has the form y=kx. Thus, we need to simplify to isolate y to see if it is direct variation. Thus, we obtain: $6y=18x \\\\ y=3x$ This does have the form y=kx, so it is direct variation. k is the constant of variation, so we know that the thing x is being multiplied by, 3, is the constant of variation.
