solve the ode & graph the phase plane
The image displays a system of differential equations:

\[
\begin{cases} 
\dot{x} = -5x + 2y \\ 
\dot{y} = x - 6y 
\end{cases}
\]

This system describes the rates of change of two variables, \( x \) and \( y \), with respect to time. The equations are commonly found in mathematical modeling contexts, such as in the analysis of dynamic systems in engineering or the natural sciences.

Expert Solution
Step 1: Description of given data

We have given system of DE's

x apostrophe equals negative 5 x plus 2 y
y apostrophe equals x minus 6 y

It can be written as

open square brackets table row cell x apostrophe end cell row cell y apostrophe end cell end table close square brackets equals open square brackets table row cell negative 5 x plus 2 y end cell row cell x minus 6 y end cell end table close square brackets

open square brackets table row cell x apostrophe end cell row cell y apostrophe end cell end table close square brackets equals open square brackets table row cell negative 5 end cell 2 row 1 cell negative 6 end cell end table close square brackets open square brackets table row x row y end table close square brackets

Let, A equals open square brackets table row cell negative 5 end cell 2 row 1 cell negative 6 end cell end table close square brackets called as coefficients matrix.
