The question is slightly confusing but what I can tell is there are at least 3 points on the graph that are touched so it can't be asking about that since we have answers like 0, 1 and 2.
So next, we can look at the slopes aka how far the lines reach and cross. They seem to keep going on and on without stopping at any visible point on the graph. So you can say there are infinitely many solutions with any real number.
