Answer 4

Thank you so much

Answer 5

i got 1 for slope i don't understand

Answer 6

what points do I use?

Answer 7

look at the y-axis, and then the x-axis. from 1981-1985, 4 years pass. In that same amount of time, the average cost goes from 4500 - 2500. 2000/4 is the ratio of rise/run. Now, do the same for 1985-1989

Answer 8

2,500-2,000

Answer 9

yes, so 500/4

simplify 2000/4 and 500/4 to get your answer. the graph is going down and to the left so your answers will be negative

Answer 10

500/4

Answer 11

i got 500 and 125

Answer 12

yes, good job

Answer 13

so B.-500 and -125

Answer 14

thanks

Answer 15

yes

Answer 16

any time

Answer 17

is it okay if you check some answers for me I just wana know if there right?

Answer 18

sure

Answer 19

i got B.

Answer 20

youre correct

Answer 21

12,)c. 13.) D.

Answer 22

I am going practice problems for a exam and wanted to know if I am doing them right

Answer 23

for 13, A is the correct answer because it has a slope 4, not -4. parallel lines always have the same slope.

Answer 24

yay :)

Answer 25

is 12 correct?

Answer 26

hold on

Answer 27

I get B for #12

Answer 28

thats strange i even put it in wolfam alpha

Answer 29

after putting it in point-slope form, I get

y = 3/14x + 33/7

y - 3/14x = 33/7

correct so far?

Answer 30

yesssss

Answer 31

then multiply by 14 or -14?

Answer 32

not sure how to get it to general form

Answer 33

what did you put into wolfram?

Answer 34

nvm, Im still pretty sure B is right, because if you multiply both sides by -14

you get 3x - 14y = -66

Answer 35

the graph of 3x - 14y = -66 is the same as y - 3/14x = 33/7

Answer 36

i used http://www.mathportal.org/calculators/analytic-geometry/two-point-form-calculator.php

Answer 37

yes, you get 3x - 14y + 66 = 0

but if you subtract 66 from both sides you get

3x - 14y = -66, which is B

Answer 38

i am so stupid

Answer 39

lol, no, it's okay. this stuff is hard. and dont worry im stupider :p

Answer 40

1 more please

Answer 41

kk

Answer 42

a ski lift runs to the top of a hill has a rise to run ratio of 5/7

Answer 43

purple. purple is the answer :p

Answer 44

the horizontal distance from the button of the lift to the center of the mountain is 6,000 ft

Answer 45

how high is the hill

Answer 46

i got 4,285

Answer 47

5/7 = x / 6000

where x is the height of the mountain

30000 = 7x

30,000 / 7 = 4285.7

so if you are rounding up it would be 4286

Answer 48

any questions?
