Answer:
0 solutions
Explanation:
The question in a nutshell is basically asking what solutions intersect each other. As (I assume) you have drawn out, they do not intersect at all, meaning that there are 0 solutions.
If you were not given a graph, you would have to set the equations equal to each other. If the number does not equal each other, then they are not solutions of each other. If it does, it is a solution. In this case, it is not.

y=-3x-6
