## The hidden indicators of players in FIFA Online 4

The hidden traits of players in FIFA Online are quite important factors, not only contributing to the perfection of the players but also the factors that help create a perfect squad.

From two straight lines (or vector) in a 2D plane, we can find their intersections to calculate the angle of reflection and direction of travel.

I have two points A (x1, y1) and B (x2, y2) form a straight line, to create a linear equation from these two points, we need to calculate the inclination of the line (slope) by the formula:

a = (y2 - y1) / (x2 - x1)

Replace x2, y2 with two variables x, y:

a = (y - y1) / (x - x1)

=> y - y1 = a (x - x1)

Or:

y = ax + (y1 - AX1)

Set b = y1 - AX1, we have:

y = ax + b

We have two equations straight line

(1): y = a1x + b1

(2): y = a2x + b2

We can calculate the intersection of them by finding the intersection of x before:

a1x + b1 + b2 = a2x;

=> X (a1 - a2) = b2 - b1

=> x = (b2 - b1) / (a1 - a2)

Once you have x, we would like to (1) or (2) to calculate y.

To check two intersecting straight lines can not we just check point {x, y} of both line segment or not .

Also we need to rule out cases of two parallel lines or overlap, then their value will equal slope.
