First, start off by finding your slope. Your slope will be change in Y divided by change in X, which would be Y2-Y1/X2-X1.
3- -1/ 2-0
Since you're subtracting a negative, that turns into addition.
4/2 = 2
Now you know your slope is 2. Next you can use your equation y=mx+b to find your b, or your y intercept. You can use one of your two pairs of points to plug in x and y. Plug your slope in for m as well.
Y=mx+b
3 = 2(2) + b
3 = 4 +b
-4 -4
-1 = b
Now you can plug in your y intercept and slope for your equation!
Y=2x-1
The answer is 0.071.
The chances of drawing an ace in the first draw is 4/52. The chances of not drawing an ace in the second draw is 48/52. The chances of getting only one ace in the two draws can be solves using this equation:
P(X=1) = (4/52) * (48/52)
= 192/2704
= 0.0710059 or <span>0.071

It's saying that on every other stop(with even numbers)you add 2 people, and on all the other stops(odd numbers)you subtract 5 people. Be sure that you start with 18 people on the bus! Keep doing this until there is no more people on the bus!
