Question

Graph the equation 2x - y = 9 plotting points

Answer 1

We want to graph the equation;

`2x-y=9`

Firstly, let us express the equation in slope intercept form.

`y=2x-9`

To get the points on the graph, let us find the corresponding values of y at x=0 to x=10 (interval of 2);

`\begin{gathered} at\text{ x=0;} \\ y=2(0)-9 \\ y=-9 \end{gathered}`
