Can some answer these for me please?
Do the following equations represent direct variations? If so, find the constant of variation
1. 3x-4y=9
2. y=1/5y
3. 8x=4y
thanks
Please post complete sentences and show your work.
Question #1 asked "Do the following equations represent direct variations? If so, find the constant of variation
1. 3x-4y=9"
and when asked to post your solution, you posted, in three separate posts,
"y=1.5? "
"y=3? "
"So no its not?"
The first two make no sense because you were not asked to find a value of y. The last makes no sense because it is not a complete sentence- "so no its not" what?
Since the questions asks, first whether or not the relation given is a "direct variation", you should start by stating what a direct variatio is and then show how the given relation does or does not satisfy that. If it is a direct variation, then you should give the constant of variation, which is NOT "y".
