原题: How Many Points of Intersection? We have two rows. There areadots on the top row andbdots on the bottom row. We draw line segments connecting every dot on the top row with every dot on the bottom row. The dots are arranged in such a way that the number of internal intersecti...
goal we must not allow more than two line segments to intersect in a point. The intersection points on the top row and the bottom are not included in our count; we can allow more than two line segments to intersect on those two rows. Given the value of a and b, your task is to c...

How many points determine a unique line?Line:A line is a set of points in the cartesian plane in a straight direction which satisfy an equation of one degree between y and x. Every pair of two points will have a unique line passing through them....
required. Time required to find all intersection points will vary depending on the complexity of the equations that need to be entered and how many points need to be found. For two simple equations with only one intersecting point, finding the intersecting point will take approximately two ...
