st(1) no direction of line is given - slope? x-intercept >1 hence can be anything more than 1 Not Sufficient
st(2) direction is given a=-1/10, the line is somewhere close to the origin steep, but we don't we where the line starts and whether it crosses the x-abscess at the point to cross the circle C Not Sufficient

Combined st(1&2) still not sufficient, the line may cross the circle but may be upper or downward placed around the circle Not Sufficient
