Answer 7

got it, the range?

Answer 8

doesnt it represents the people that showed up?

Answer 9

the range is the set of all values of the y-variable

Answer 10

got it, can you help me out with #3?

Answer 11

ok!

Answer 12

Thanks so much !

Answer 13

I dont know how to graph this

Answer 14

in order to get your graph, we have to use the table above, namely we have to draw the subsequent points:
(1,8), (1,35), (3,62), (4,89)

Answer 15

oops..(2,35)

Answer 16

Okay, can you draw it out I dont really understand

Answer 17

still there?

Answer 18

here is the requested graph:

Answer 19

I think that your graph is a line

Answer 20

the main feature, is that your line passes at the origin of the coordinate system

Answer 21

okay so i would right "1 2 3 4" under my graph?

Answer 22

we can write its formula, making this conjecture:
y=A*x+B

Answer 23

that's right!

Answer 24

okay (: I'm ready for #4

Answer 25

your graph, as I wrote before, passes at the origin of the coordinate system

Answer 26

I think that it is the one of the features.
Another feature, is that it is a straight line

Answer 27

OH, but what about #3

Answer 28

it is a straight line, since we can see it from the same graph, even if it is an experimental graph

Answer 29

thank you! i already have # 5 so i just need # 6-12

Answer 30

we have to start from this formula:
y=A*x+B, where A, and B are two coefficient to be determined

Answer 31

coefficients*

Answer 32

if we set x=1 and y=8, I get:
8=A+B
