1. Y=8x

Ans: yes, it represents direct variation because

its in the form Y=kx. Constant of variation: 8

2. Y=2x+1

3. 3x+y=6

Please help, not too sure if I am understanding this correctly. Completed first problem.

**MathMate**, Friday, January 4, 2013 at 10:41amFirst problem is correct.

A direct variation will have the y-intercept as zero, so it is in the form

y=kx, where k is a constant.

In other words, a direct variation is a straight line that passes through the origin.

Q2 and Q3 are not direct variations, because the y-intercepts are 1 and 6 respectively.
