9. Choose a topic that interests you or a question you would like to attempt to answer. Describe how you would go about collecting data on the topic, and then explain how you would display your data in a graph. Tell why you chose the particular graph.

En \( R^{2} \) suponga que \( (x)_{B_{1}}=\binom{2}{-1} \), donde \( B_{1}-\left\{\binom{1}{1},\binom{2}{3}\right\} \). Al escribir \( x \) en términos de là base \( B_{2}=\left\{\binom{0}{3},\binom{5}{-1}\right\} \) queda \( (x)_{B_{1}}=\binom{-\frac{1}{3}}{\beta} \) ¿Cuánto vale \( \beta \) ?
