Question 398299
I have to solve each system by graphing, I have to find the number solutions and write the point. The equations are 3x+3y=12 and 2x+2y=2 
...
3x+3y=12
/3
x+y=4 
generate values for y & x
x=0, y=4 (0,4)
y=0,x=1  (4,0)
2x+2y=2
/2
x+y=1
x=0, y=1  (0,1)
y=0,x=1    (1,0)

...
{{{graph(300,300,-5,5,-5,5,y=-x+4,y=-x+1))}}}
...
The lines are parallel to each other . So there is no solution to the system
