Answer 2

what do you think?

Answer 3

i really dont know, i would guess 60

Answer 4

I don't know the answer yet, but we have the way to find it out, don't guess.
first off, write down the equation of the line, base on 2 points (3,30) and (4, 40) what do you have?

Answer 5

do you know how I have those points? on the graph

Answer 6

well those points are on the graph, but what about point on (1,10)?

Answer 7

on the graph, you don't have (1,10), just (1, 11or bigger)

Answer 8

so, the best way is choosing the integer coordinate points

Answer 9

okay so (3,30) and (4, 40)

Answer 10

how about the slope of the line?

Answer 11

slope is 1/10

Answer 12

nope, \(slope~m= \dfrac{y_2-y_1}{x_2-x_1}\)

Answer 13

40 - (30) = 40 + + 30 = 70
4 - (3) = 4++ 3 = 7

Answer 14

70
---
7

Answer 15

not that, calm down. you get 10, that's correct but not on that way
\[m = \frac{40-30}{4-3}=10\]

Answer 16

got it?

Answer 17

ok so i was right before, 10/1?

Answer 18

reread, yours before is 1/10, not 10/1 hehehe

Answer 19

or just 10

Answer 20

oh yes lol i was confused

Answer 21

hahaha... ok, now pick one point to plug in the line equation, I choose (3,30)

Answer 22

OK?
