    you could have actually solve for it. if you try to find the slope of each of them, you will find they both have a slope of -1/3. and because both their y-intercept is at 4, they are the same line

    no. infinitely many because they are the SAME line. all there points will be the same

    0 is for parallel lines. 1 is for two intersecting lines. 2 is impossible. two lines cant intersect at two points. they wont even be lines
