An employee at a department store is stocking cell phone cases. He has a box of 80
cases; among the 80 cases, 40 are black, 10 are white, and 30 are pink.
If he reaches into the bag randomly and removes one at a time, what is the probability
that the first three cases are all pink? Write the probabilities and your answer as
fractions.

answerthe vertex form

step-by-step explanation:

correct answer:

b.(19,-2)

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

the answer to question 1 is -8, 28.
