Hi,

I've just started Linear Algebra

I have one question i'd like some help with.

The line l $\displaystyle Oe_{1}e_{2$ is described by the equation $\displaystyle 2x_{1} + 3x_{2} = 0$

Find an equation for the line in $\displaystyle OeŽ_{1}eŽ_{2}$

if $\displaystyle ~~\begin{cases} eŽ_{1} = \frac{1}{13}(5e_{1} + 12e_{2}) \\

eŽ_{2} =\frac{1}{13}(-12e_{1} + 5e_{2}) \end{cases}$

Any advice?
