Graph the equations to solve the system y= 1/2x + 6 y = -1/2x + 4

y=5, x=-2

Step-by-step explanation:

From the graph (attached), we can see that y=5, x=-2.

We can also solve system through algebra. (the easier and faster way)

y=1/2x+6

y=-1/2x+4

Substitute y with the first equation.

1/2x+6=-1/2x+4

1/2x+1/2x=4-6

x=-2

Then, substitute x with -2 in the equation.

y=1/2(-2)+6

y=-1+6

y=5
