question 9

Multiple Choice

Determine whether the variation model is of the form $y = k x$ or $y = \frac { k } { x }$ and find k.Then write a model that relates y and x. $$\begin{array} { | c | c | c | c | c | c | } \hline x & 5 & 10 & 15 & 20 & 25 \\\hline y & - 1.5 & - 3 & - 4.5 & - 6 & - 7.5 \\\hline\end{array}$$

• A) \(y = - \frac { 3 } { 10 x }\)
• B) \(y = \frac { 10 } { 3 } x\)
• C) \(y = - \frac { 3 } { 10 } x\)
• D) \(y = \frac { 3 } { 10 } x\)
• E) \(y = - \frac { 10 } { 3 } x\)
