Answer 1

Given:

$\begin{gathered} x+2y=1 \\ -2x+y=-4 \end{gathered}$

Find: draw the given lies on the graph.

$\begin{gathered} x+2y=1 \\ \frac{x}{1}+\frac{y}{\frac{1}{2}}=1 \\ \end{gathered}$

so the line passes through the point

$(1,\frac{1}{2})$

and

$\begin{gathered} -2x+y=-4 \\ \frac{x}{2}+\frac{y}{-4}=1 \end{gathered}$

so the line passes through the point (2,-4).
