Question

MEDAL for help in geometry!

Need help on part D

Answer 1

@Loser66

Answer 2

where are (1,2), (3,5),(5,8),(7,11)?

Answer 3

What do you mean?

Answer 4

@Nnesha @TheSmartOne

Answer 5

(1,2) is a point. Where is it ?

Answer 6

Somewhere around there

Answer 7

I graphed all of the points and I do see that there is a constant rate of change.

Answer 8

so, the graph is a straight line, right?

Answer 9

Yes

Answer 10

what is the equation of that line?

Answer 11

I am going to figure it out right now

Answer 12

y = 3/2x + 1/2

Answer 13

fast!! good

Answer 14

I used the midpoint formula to figure out part c

Answer 15

remember!! you start watching when it is at x =1. Then after 25 minus, x =26, right?
so, when x =26, y =?

Answer 16

well it's given in increments of 10 seconds

0 sec (1,2)
10 sec (3,5)
20 sec (5,8)
30 sec (7,11)

Answer 17

Yes, you are right, but how about d? You should know how to use a general form to solve the problem. With equation of the line, you can trace it EVERYWHERE.

Answer 18

do you want for me to solve for y when x = 26?

Answer 19

:)
This is your problem. You do whatever you like.

Answer 20

i get that y = 39.5

Answer 21

good

Answer 22

but it doesn't make sense if i plot it though

Answer 23

oh, I got where you get it wrong. ok

Answer 24

for x axis, every 2 units represent for 10 minutes, right?

Answer 25

yes

Answer 26

so, the ratio is 1/5, ok?

Answer 27

yes

Answer 28

5/1 for minutes.

Answer 29

ok
