Answer:
(-3,5)
Explanation:
To solve the system, graph the two equations.
x +y= 2 becomes y=2-x has m=-1/1 and b=2. Start at (0,2) on the y-axis and plot a point. Then move down 1 unit and 1 unit to the right. Plot a point and connect.
y=x+8 has m =1/1 and b=8. Start at (0,8) on the y-axis and plot a point. Then move up 1 unit and to the right 1 unit. Plot a point and connect.
The solution is the point (x,y) where the two lines intersect. By the graph below it is (-3,5).
