I believe the answer should be 6x+3
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
This question does not really make sense.
How ever I’ll try to respond to this with the best of my ability.
y=mx+b is nothing but slope intercept form.
M is slope value. B is the y-intercept.
There is really no need for x-intercepts in slope intercept form.
Hope this helps. :)
