Question 1018852
solve each system by graphing the problem is 
2x - y= -5
-2x - y= -1
------
Graphing 2x - y = -5
----
solve for "y"::
y = 2x+5
---
Plot two points::
If x = 0, y = 5 ; If x = -1, y = 3
Plot (0,5) and (-1,3) and draw a line thru them.
-------------------------------
Graphing -2x - y = -1
Solve for "y"::
y = -2x+1
Plot two points:: (0,1) and (-1,3)
------
Note that (-1,3) satisfies both equations.
