You can put this solution on YOUR website! First, get it into slope-intercept form: y = mx+b
m = slope
b = y-intercept
.
3y = 12
y = 12/3 = 4
.
Now pick two points to define a line: say x=1 and x= 4
.
When x = 1, y = 4
When x = 4, y = 4
.
Hmmm....
It appears this is a horizontal line, which means the slope=0.
Observing y = 4 we see that this is the same as y = 0x + 4, which is slope=0.
.
.
Done.
