Which graph represents the solution to the given system
Y=-x+2
Y=1/2x+8
y = 1 / 2 x + 8
Multiply both sides by 2
2 y = x + 16
y = - x + 2
+
2 y = x + 16
___________
3 y = 18
y = 18 / 3
y = 6
Put this value in equation y = - x + 2
6 = - x + 2
Subtract 2 to bith sides.
4 = - x
- x = 4
x = - 4
The solution is:
x = - 4 , y = 6
You can write solution as ( - 4 , 6 )
