Solve by graphing. Write no solution or infinetly many solutions where appropriate.

----------------------
Graph y = x-1
Let x = 0, then y = -1 giving you point (0,-1)
Let y = 0, then x = 1 giving you point (1,0)
Plot those points and draw a line thru them.

=========================================
Graph y = -x+7
Let x = 0, then y = 7 giving you point (0,7)
Let y = 0, then x = 7 giving you point (7,0)
Plot those points and draw a line thru them.

=========================================
Put both on the same axes and try to find the point of intersection.

---
Solution: (4,3)
