Question 914534
2x+y=-6
 y=-1/2x-3
...........
I.  Graph each Line (Determine 2 Points on each line, Plot and connect)
y = -2x - 6, P(0,-6) and P(-3,0) Plot, connect
y = (-1/2)x - 3, P(0,-3) and P(-6,0)Plot, connect
II. Their Intersection is the SOLUTION for ths System: Written as Ordered Pair(x,y)
In this Example: (-2,-2)is the Solution for the System
