The first equation is already how we want it: y and x are on opposite sides, and y is multiplied by 1.
The second one you'll have to isolate y (which will make it easier to graph). First, you want to get x on the opposite side of y, so you'll add x to each side, giving -2y=x+6. Second, you want to get y as just y (we don't mind what happens to x), so divide each side by -2, giving the equation y=-1/2x+6.
Do these lines cross paths? You can check by plugging in the equations on wolfram alpha as "y=-1/2x-1 , y=-1/2x+6". If they do, the point at which they cross is the solution of the system. If not, then the system has no solution.

Do you mean you’re having an issue with drawing the graph out yourself? There is no solution, you got that right. To draw the graph you pick arbitrary values of x and plug them into the equation to find y. Maybe use like -5,-4...5. All you really need to do is show that they run parallel. Let me know if I understood your question correctly.06/16/19

still dont understand. i drew two parallel lines and it wasn't correct.06/16/19

nevermind. I got it! thank you for your help06/16/19

You’re welcome, glad I could help.06/16/19

it doesn't so no solution. but how would i find the points to graph, thats where i have the issue.06/16/19
