What is the slope of the line in the graph shown?

A. -2
B. -1
C. 1
D. 2

-2 slope so A

Step-by-step explanation:

to find slope it be rise over run

to get from (1,1) to (0,3) you have to rise 2 and go back 1

so numbers form it be 2/-1 what is the same as -2 slope

also you can tell its a negative slope cause everything is descending down.

There is 2 steps to do it. one is using rise/run and other is y2-y1/x2-x1

1st step: It's -2 cause the rise is -2 and run is 1  and the slope formula is rise/run which is -2/1=-2.

2nd step: (0,3)(1,1)

x1=0

y1=3

x2=1

y2=1

1-3/1-0

-2/1

-2

For both of them, we get -2. So, the answer is -2

2.   never

3   .08c = 7.50+.05c   250 pages

step-by-step explanation:

1.   sometimes

the theoretical probability of rolling a 1 is 1/6.   perhaps you got really lucky and never rolled a 1   in those 60 times.   your experimental probability is 0.   or perhaps you rolled a 1   20 times.   your experimental probability is 20/60 is 1/3.     it really just depends on how you rolled in that experiment.

2.   never

the probability of the event occurring is 1.   that is being 100 % sure it will happen.   that is the maximum amount of confidence we have.

3.   no customer card cost:   .08 times number of pages

customer card cost:   7.50 + .05 times number of pages

we want to find when it costs the same amount, so we will set these equal

let c = number of pages

.08c = 7.50+.05c

subtract .05c from each side

.08c-.05c = 7.5+.05c-.05c

.03c=7.5

divide each side by .03

.03c/.03 = 7.5/03

c =250  

the cost is the same at 250 pages

it has to have an angle of 90 degrees
