F(x) = a.x . We ha to calculate a.

Back to the table, let's rewrite the coordinates

A(0,0)
B(2,-1)
C(4,-2)
D(7,-3.5)
We know that constant is called slope or coefficient is equal to:
a=y/x
Apart from A, in each of the coordinates y/x =-1/2 & this is the slope of the equation f(x) = (-1/2)x

Your expected win from this bet would be about -0.05, meaning that you can expect to lose 5 cents on each $1 bet.

To find this we multiply the probability for each bet times $1. Remember in Roulette, there are 18 red, 18 black and 2 zero spaces.

(18/38) x 1 + (20/38) x -1 = -0.05
