Determine the slope & the y-intercept of the following graphs.

Step-by-step explanation:

remember that slope is change in y over change in x or (y2 - y1)/(x2 - x1)

so let’s look at two points (1,5) and (2,1)

(5-1)/(1-2)

4/-1

-4

the slope is -4

to find the y intercept, look where x = 0 and move up or down the y axis

in this case when x = 0, y is 5

so the y intercept is (0,5)

apply this to the second problem

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
