Answer 1

they are the labels of the axes

Answer 2

i think im not sure, i really don't understand it

Answer 3

one variable, the horizontal one, is time
the other one is the number of handbags (jeez really? when was your book written 1956?)

Answer 4

lol hahahaha idk nd ok

Answer 5

that is clear right? they have labelled them for you

Answer 6

no they haven't

Answer 7

yes they have
look at the axes
below one it says "time"

Answer 8

and along the horizontal axis they have written "number of handbags"

Answer 9

therefore on variable it time
the other is number of handbags

Answer 10

they are related that at time 1 => number of handbags, time 2 (=2x time 1) => 2x number of handbags; time 3 => 3x number of handbags. After that she didn't seem to buy any handbags anymore over time.

Answer 11

they axes are not labelled with units, so you don't know the time or the number of handbags in this question

Answer 12

no, but you can see that the distance between moment 1 (which might be 3 months, 2 years, whatever given time) and moment 2 is the same distance from 0 to moment 1. So you do know it's a double amount of time. Same logic can be used on the rising amount of handbags. You don't know exactly how many bags at moment 1, but you can see it doubled at time 2, and tripled by time 3.

Answer 13

yess it says that the graph shows how many mandy had in one day.

Answer 14

So time 1= 1 day, time 2 = 2 days, time 3= 3 days. Normally the intervals of the x-axis (horizontal) are the same intervals for the y-axis (vertical). And the stairs look like squares. So after 1 day -> 1 handbag, after 2 days -> 2 handbags, after 3 days -> 3 handbags.

Answer 15

making a rather broad assumption that the axis are labelled are labelled to scale

Answer 16

Well you can always write down 'let's assume they are labeled to scale'.

Answer 17

ok but lik lol i have to explain this and its hard

Answer 18

this is the entire questions

\[\bf\text{What are the variables?}\]
\[\bf\text{ Describe how the variables are related to the points on the graph?}\]

right?

Answer 19

Do you have a piece of paper at hand with squares on it? Draw a horizontal line on it, and then a vertical one that crosses the horizontal one. Write "time (days)" underneath the horizontal one at the far right. Write "number of handbags" at the left top of the vertical one. Now you will use a scale. Let's say 4 squares to the right = 1 day. Start counting your squares from the intersection between the horizontal and vertical lines (that is point 0). When you counted 4 squares to the right, starting from 0, put a notch across the horizontal line and write 1 there. Count another 4 squares to the right, put another notch and write 2. Repeat and put a notch for the 3rd day.

Now you'll do the same for the vertical one. You start counting from point 0, count 4 squares upward and put a notch on the vertical line and write 1 there. 4 more squares upwards you put a second notch and write 2 there. Repeat for a 3rd time and write 3.

When you are done, you've created 2 axis that use the same scale.

Answer 20

yes
@satellite73

Answer 21

ok @sweetsunray

Answer 22

you can do what @sweetsunray said
that looks like a good idea

but more briefly the variables are the ones listed and at some point mary buys a new bag (or bags) adding to her total

Answer 23

ok thanx but i'll jus put that i don't understand this, and thanx for all yall help !! XD

Answer 24

That's why I gave the drawing exercise... By doing it you can start to understand what these things are.

Extra something to help you practice and understand, once you've drawn the lines and the notches with numbers (the scales). Let's say that Cindy bought 1 handbag on the second day. Try to mark it in the field.

Answer 25

ok thanx very much
