how can i solve the system by graphing.
E1: x + y = 4
E2: �x + y = 2
:
For E1, let x=0 and y=?
0+y=4
y=4 Plot (0,4)
Now let y=0 and x=?
x+0=4
x=4 Plot (4,0)
Connect your points and you have this line:

For E2, let x=0 and y=?
-0+y=2
y=2 Plot (0,2)
Now let y=0 and x=?
-x+0=2
-x/-1=2/-1
x=-2 Plot (-2,0)
Connect these points and you have a second line.

The solution is their point of intersection: (1,3)
Happy Calculating!!!
