We want to graph the equation;
[tex]2x-y=9[/tex]Firstly, let us express the equation in slope intercept form.
[tex]y=2x-9[/tex]To get the points on the graph, let us find the corresponding values of y at x=0 to x=10 (interval of 2);
[tex]\begin{gathered} at\text{ x=0;} \\ y=2(0)-9 \\ y=-9 \end{gathered}[/tex][tex]undefined[/tex]
