Question

Does the equation represent a direct variation? If so, find the constant of variation 5x = -3y

Answer 1

I really don't understand any of this..

Answer 2

\(\bf \begin{array}{cccllll}
\textit{something }&\textit{varies directly to }&\textit{something else}\\ \quad \\
\textit{something }&={\color{red}{ \textit{some value }}}&\textit{something else}\\ \quad \\
y&={\color{red}{ n}}&x&\implies y={\color{red}{ n}}x
\end{array}\)

so... solve the equation for either variable, see what you get

Answer 3

a direction variation means, something varies with a multiplier in relation to something else

say you like chocolate cookies, and your brother too more so
so for every cookie you eat, he eats 5
if you eat 2 cookies, he eats 10
if you eat 5 cookies then he eats 25

so a function for that would be say brothercookie = yourcookie * 5
or y = 5x

Answer 4

erk... direct variation that is

Answer 5

yes k =-5/3
