Question

Medal for help :)
For the data in the table , does y vary directly with x? if it does write an equation for the direct variation.

Answer 1

so.... does it?

Answer 2

yes

Answer 3

@HELP!!!!

Answer 4

well.... let's take a look at the 1st point then

x = 8 y = 11
so \(\bf \begin{array}{cccllll}
\textit{something }&\textit{varies directly to }&\textit{something else}\\ \quad \\
\textit{something }&={\color{red}{ \textit{some value }}}&\textit{something else}\\ \quad \\
y&={\color{red}{ n}}&x&\implies y={\color{red}{ n}}x
\end{array}\\ \quad \\
x= 8\qquad y=11\implies 11={\color{red}{ n}}(8)\)

solve for "n", or "constant of variation"
and then plug it back in the equation

Answer 5

B

Answer 6

n = B? well.... I think is a constant

Answer 7

that's my answer

Answer 8

y=06875x

@juniorEinstein1: to live up to your user name, you're going to need to invest more time and effort into problem solving. Ignoring jdoe's question and then asking one person after another for help will not help you much in the long run.
If you truly want to learn how to solve this kind of problem, go back to jdoe's input and see what you can come up with as a value for 'n'.
