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 \\ (x)/(1)+(y)/((1)/(2))=1 \\ \end{gathered}`

so the line passes through the point

`(1,(1)/(2))`

and

`\begin{gathered} -2x+y=-4 \\ (x)/(2)+(y)/(-4)=1 \end{gathered}`

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