is it possible that an equation could have more than two points of intersection in a line and parabola , if so, how?

If you're finding the intersection of a line and a parabola, or a parabola and a parabola, there can be 0, 1, or 2 points of intersection. If you're finding the intersection of higher degree functions, such as x^3, x^4, etc., the graphs can have more curves, and thus, you can have more points of intersection! Try playing around with graphs on Desmos to see!

how would we know if they wont intersect? is there any way to know that?

Yes; if you do the Quadratic Formula, and the portion inside of the square root ( b^2 - 4ac...called 'the discriminant') is negative, there will be no real solution since the square root of a negative number does not exist. This means the two graphs do not intersect! (This type of solution is called 'imaginary', which comes up a lot in Algebra 2 and beyond!)
