The point-slope form:

$y-y_1=m(x-x_1)\\\\m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (-1, 3) and (2, -2). Substitute:

$m=\dfrac{-2-3}{2-(-1)}=\dfrac{-5}{2+1}=-\dfrac{5}{3}\\\\y-3=-\dfrac{5}{3}(x-(-1))\\\\\boxed{y-3=-\dfrac{5}{3}(x+1)}$

Chance of getting number greater than 4 on one roll:

Either getting a 5 or 6

2/6 probability

2/6 = 1/3

If we roll the cube 12 times, the probability of getting a number greater than 4 is 1/3 of the time

12 * 1/3 = 4

She is expected to get a number greater than 4, 4 times
