Hi so im in elementary and i have these simultaneous linear equations which i am told to solve graphically. The equations are x-y=-3 and x-2y=-1. How do i derive the range for my graph from these equations. PLEASE HELP ITS MY HOMEWORK AND I AM LOST! Thank you:)

First, transform both equations:
(1) x - y = -3 => y = x + 3
(2) x - 2y = -1 => y = 0.5x + 0.5
Now, you can graph these functions and see whether and where they meet.
In addition:
In order to determine your functions' range you have to know what range of x may be used. It seems that there are no restrictions so x could be any real number. Since your functions are both linear the resulting range would also be within any conceivable real numbers. I hope that cleared things up a bit.
