start by writing the equation in standard form
[tex]-x+2y=0[/tex][tex]\begin{gathered} 2y=x \\ y=\frac{x}{2} \end{gathered}[/tex]
then give values to x
for x=2
[tex]\begin{gathered} y=\frac{2}{2} \\ y=1 \\ A\colon(2,1) \end{gathered}[/tex]
for x=4
[tex]\begin{gathered} y=\frac{4}{2} \\ y=2 \\ B\colon(4,2) \end{gathered}[/tex]
