What is the slope of the line that passes through the points (0, -4)) and (-2, -1)

Step-by-step explanation:

y = mx + b

m is the slope (what you want)

b is the y-intercept, which is the value of y when x = 0

Oh, right, we already have b, isn't that great!

Given point (0, -4), so b = -4

Point (-2, -1), where x = -2 and y = -1

-1 = -2m -4 (solve for m)

3 = -2m

m = -3/2

Check:

y = -3x/2 -4

y = -3(-2)/2 -4  -> should get y = -1

y = 3 -4 = -1

Yay, we have the answer!

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
