Answer:
The slope would be -x
Step-by-step explanation:
The second number in the equations y=mx+b is always the slope unless you have to plug in number and do all kinds of stuff but that's not whats in the problem now.
Answer:
x=12, y=6
Step-by-step explanation:
Very simple!
Just substitute 0 for y and solve for x!
(anything times 0 equals 0!)

Now you can do the same thing but substitute 0 for x!


Hope this helps!
